Pros: * I’ve been a Logitech devotee for at least twelve years. Corsair’s peripherals never just made enough of an impact on me to switch over to their mouse lines, keyboards or headsets, and I’ve tested a good number of them. They were always missing something that I deemed indispensable. Mostly, their mice were aimed at claw grippers. And I never much liked their software, the Corsair Utility Engine, due to its overwhelming settings and often muddying options. However, my opinion now may be different after having spent more than a week with Corsair’s Scimitar RGB MOBO/MMO Gaming mouse. * - First off, the Scimitar is an utterly gorgeous mouse. Aesthetically, it may be one of the best-looking mice I’ve ever laid eyes on. Its undertone, matte black looks clean and sleek, avoiding fingerprints. Its side buttons look fantastic and industrial. The ring finger tactile coating fits despite its rough-plating appearance. The LED that protrudes out of the mouse to highlight the side buttons helps make the mouse congruent. Speaking of the LEDs, they are marvelous. They light up each side button with back-lighting; a spotlight of green in front of the side buttons (see Cons); the Corsair logo is beautifully lit; the mouse wheel has a subtle side glow, and, quite unnecessarily hidden, there’s also a grilled LED on the front of the mouse, sadly rarely to be witnessed. All four of these LEDs can be controlled independently and set to be a solid color, gradient, ripple, or pulse from the CUE software. The Scimitar pulls off its awesome gaming aesthetics; you can’t help but stare at it. - The mouse weighs about 147 grams. For my personal preference, it’s perfectly weighted with easy height lift. The mouse cable is braided, giving very little resistance when moving rapidly. The massive PTFE pads on the bottom instill extremely smooth movement and glide if you prefer. Control over this mouse couldn’t be better. I have very long, wretched fingers, and all of them end up laying perfectly over the top of the mouse. My fingers do not touch each other like they do in the G602’s case. This gives you even more control and comfort. I’ve always used a palm grip, and surprisingly, this mouse fits a palm grip without any drawbacks. Also, trying it with a claw grip results in a good experience as well. So I can honestly proclaim that whether you’re a claw or palm gripper, this mouse should work for you. The main reason for this compatibility is due to what Corsair calls the “Key Slider.” It’s a brilliant feature that enables the 12 side buttons to be repositioned up to eight millimeters in either direction using an Allen key at the bottom of the mouse. I found that I had to reposition the Key Slider all the way to the front for my thumb to be optimally positioned, while a claw gripper or someone with shorter fingers may prefer it closer to the back. Corsair’s attention to detail here deserves lauding. Its exterior coating feels extremely comfortable, with a soft rubber-like tactile feel. - Between the 17 customizable buttons (in reality, 14) and Corsair’s CUE software, the Scimitar is highly customizable. They are indeed right when they brand it as an MMO / MOBA mouse. With the twelve side thumb buttons, you can bind twelve spells or hotkeys, and then some if you use a keyboard combo like Shift. Having essentially 24 different hotkeys at the touch of your thumb is overwhelming. Corsair did a decent job trying to implement a difference in tactile feel for these 12 keys so you can tell the difference of what row you’re on, but I still think they could have made it even better (see Cons). The actual press of the keys aren’t bad but they take a little more force than I would have preferred. However, the mechanical switches of these keys’ click and the haptic response are rewarding. After getting used to the mouse, I rarely made a mistake in which side button I wanted to click, but know that there is a learning curve with it, and accidentally clicking the wrong one could mean death in an MMO or MOBA. - Corsair’s CUE software offers a dizzying amount of customizable options. It isn’t the best software out there (see Cons), but it will give you a plethora of settings to customize and define for your unique use. I found myself hovering around 4k DPI, though the mouse offers up to 12k. On my G602 I have no issues being at 3k, even with three monitors. Just because a mouse can go to 12k makes it no better. But the high ceiling allows for it, so that never hurts. I just can’t imagine someone gaming at 12k DPI, but hey, to each their own. - The middle scroll wheel feels great when scrolling, with a noticeable bump for each level (see Cons).

Cons: - The two main left and right click offer good resistance; however, I like mine slightly softer, more responsive, and less stiff. Nonetheless, possibly after breaking the mouse in for longer than a week or two, and more like a month, the main two buttons may pan out to be more flexible. - Though the lighting options and configurations are astoundingly customizable, Corsair oddly left out the fifth lighting zone on the mouse, one of the most prominent LEDs on the mouse, the one that is situated in front of the 12 side buttons. It stays at Green no matter what you do. It’s hard to complain about it, but it’d be nice to have the option of changing that considering you can change all of the other four lighting zones. - There is a learning curve to the 12 side buttons. If you’re a past Naga user, it may be s much easier transition. But I did get lost often with my thumb. Although, even worse than getting lost was having to focus where on my thumb to press. Instead of it coming to me second hand and instinctively, I had to take a second to control my thumb. This time diminished the longer I used it, but I see the delayed response always being an issue. The other problem: even though Corsair textured the columns of the buttons to know what column you’re on, it’d be better to add a small bump or bar like in Home Row to know which row you’re on. Possibly, situated on the 2 and the 8 or 5 and the 11 key. It would help immensely with guidance. - When reaching over my middle finger to click the middle button, it takes more force than it should, noticeably different from my other mouse. It may be a positioning issue or just a personal, unique anomaly. - Even though the CUE software has tons of options, it isn’t nearly as user-friendly as other peripheral software that’s on the market. A good case in point is Logitech’s Gaming Software, which I find to be much more straightforward and streamlined, easier to use. Corsair has a little while to go for the software to be more digestible as opposed to overwhelming.

Overall Review: * Overall, I think the Scimitar is a great weapon to add to your arsenal if you’re an MMO or MOBA gamer. The branding speaks for itself. It has a ton of awesome feature–some of which like the Key Slider–that can’t be found in other gaming mice (that I know of; excuse me if I’m wrong on that). It sports a wealth of customizable features, awesome LEDs with the gamut of RGB options, amazing aesthetics, 12 side buttons, and terrific build quality. I highly recommend the Scimitar if you’re looking for a plethora of buttons at your disposal. *

Pros: First off, what this is. Its a gaming mouse specifically for games where lots of buttons is a good thing. Many folk will choose this to use with complex software applications like Autocad, solidworks, etc. where programming the buttons can make you more productive. Things I really like: Large, programmable buttons with a gazillion options, lots, RGB color. Dedicated DPI buttons with color indication (you'll probably want to dim this as its a bit bright) you can instantly switch from fast mouse movements to precision. Very nice connecting cable is cloth wrapped, a feeling of quality.

Cons: Corsair software (corsair utility engine) is still confusing although full featured. Programmable buttons require software be running (only the lighting scheme seems to be able to be stored in the mouse). But a slight lag when logging in to your computer can be annoying, the mouse noticeably stutters while the drivers kick into gear as computer wakes from sleep. And of course for what this mouse is all about, the thumbuttons. I think the fact that the buttons can be adjusted forward and back is great, and the buttons seem to be of very good quality. The neg, for me, is that although they are textured in a way to help you feel the difference between keys, its fairly subtle -- and you thumb is not your most touch sensitive finger.

Overall Review: Designed for games with lots of keyboard buttons to push (like WoW), but for the same reason this is a great mouse for use with applications like photoshop, autocad, etc. and other programs that use the mouse for drawing and selecting, allowing the user to keep her hand on the mouse. Great for that. I'd like to see more responsive software (or macros that are stored in the mouse itself) and better tactile cues on the thumbutton array. Otherwise, not bad, but i'll wait for V2. Or maybe just the next software/driver rev. :)

Pros: There is a lot to like about this mouse. -It has a good sensor and worked well on all services except my whit desk surface where it would think I'm making small movement when I was not -12000 DPI is great! -Cable is tangle resistant and a good length -Comfortable with good matte finish and the rubber on the right side ensures you never lose grip -Buttons provide good tactile feedback -Scroll wheel is easy to spin and doesn't keep spinning after you let go -Really like the ability to adjust the thumb buttons forward and back -Software is easy to use for the most part. I had no problems creating macros and profiles for different applications -And of course the light is fun to fool around with

Cons: There aren't many cons, more feature they chose to leave out. Missing features: - Size and weight adjustability - Wireless capability Cons -Would have like a little more of the rubber, maybe on the bottom left behind the thumb -Could have worked on more surfaces -I would prefer the thumb buttons had less resistance. I have to tighten my grip to keep the mouse from moving when I press them -The software interface is a dark grey background with light grey font. This makes some menus hard to read.

Overall Review: Q: Would you recommend this product? A: Yes Q: If there is something you would change, what would it be? A: Less resistance on the thumb buttons

Pros: • Great hand feel other than thumb, but not worth any deduction. • Smooth motion. Glides easily. • Love the customization options. • Lighting options nice. • Switchable DPI is a great help (from fast to precise or vice versa). Sometimes I need more precise motion. • Programming is way more capable than needed for my games. • Updated firmware available right away and will keep me advised of more. • Physical customization - I moved keypad from the default position to attain more comfortable position to rest my thumb on. Thanks for this option. Logitech M-570 is my general purpose non-gaming mouse. It has a huge thumb ledge in comparison, which has spoiled me. I just consider it a trade-off.

Cons: • Software (Corsair Utility Engine) not easiest to get the hang of. I am getting there.

Overall Review: I have always enjoyed Corsair products and this mouse is no exception. If you like having a competitive edge, this should be a nice addition to your arsenal so to speak. This and large bandwidth/ blazing internet speed of course. I have 30 mbps service, so it could be better. I was offered this item for review purposes. The opinions are mine so ymmv based on your preferences and needs of course.

Pros: + Adjustable key pad - The pad of 12 buttons on the side of the mouse can slide forward and backward for better thumb placement. There is a hex screw on the bottom of the mouse to loosen the key pad. Once you have it where you want it simply tighten the screw back down and you're set. I find that right in the middle works best for me. + Vibrant lighting system - Many gaming mice allow lighting customization, but often even after customizing them to your liking many of them still don't look great (dull colors, zones bleeding into one another, uneven brightness, certain zones that can't be changed which clash with certain color selections, etc..). This mouse delivers deep, vibrant colors with zones that don't bleed into one another. The Corsair logo in particular looks smooth, it honestly has the appearance of being painted on with some kind of bright glow-in-the-dark paint. I think it is the result of a clear matte finish that defuses the light, making the color across the entire logo even and sharp. There's even a vent-looking light on the front of the mouse that typically isn't even visible to the user that gets its own light zone settings. It's VERY attractive. + Sensible DPI adjustment system - The Scimitar has two distinct DPI adjustment buttons, one to raise DPI and one to lower it. Some mice have a single button which can make going down one DPI level (a normally simple task) unnecessarily complicated. That's not a problem with this mouse. + Customizable DPI indicator - The Scimitar's DPI indicator is located just forward of the side key pad. It consists of a single, somewhat large, tall, rectangular area light. At first I didn't like it because each DPI setting is indicated using a distinct arbitrary color...one of them might have been white, another one yellow, another blue, and another red (I can't remember off-hand what the actual color settings were), but that's too arbitrary for me. My RAT 7 mouse has a row of lights where more lights = higher DPI and that's probably my favorite indicator system so far, it's a system that I can understand at a glance. But the Scimitar turned out to be alright because you can change the DPI light colors to be whatever you want. I chose a color that matches my color scheme and just set it so that it gets brighter as I raise the DPI, which is a system that I can understand at a glance. + Comfortable - This fits right into the palm of my hand and nearly the entire surface has a smooth rubberized coating which feels very nice. There is also a groove for my ring finger to rest in which has a tire-tread-like textured surface. It feels nice and seems to be effective at keeping my hand position. The only things I dislike about the feel of the mouse is its lack of weight (I wish I could add some) and the side buttons don't give me a place for my thumb to grip without pressing them (a limitation of this style, I think). + Great software interface - Corsair has done a fantastic job with the software interface. It is intuitive and all seems to function as intended. I had a bit of trouble figuring out the more advanced lighting options but the basic lighting options are already vast so I didn't feel the need to trouble myself with that. Overall, the software is a must if you want to take full control of this mouse.

Cons: - Lack of physical customization options - Many premium gaming mice these days have the option of adding/removing weights, raising or extending the palm rest, adjusting thumb grips, etc.. The only adjustment this mouse includes is the key pad on the side which can slide forward or backward. I've grown accustomed to heavier mice with weights in them so this one doesn't feel as substantial to me and it would be nice to have the option of making it heavier. - Side buttons flush with one another - The fact that the side buttons are small, flush, and right up against one another makes it somewhat difficult to press one button at a time. If you are a flamenco guitar player than this probably won't be a problem at all, but if you have mildly fat fingers and not great dexterity (like me) then it could be an issue to be aware of. Personally, I would prefer if the buttons were domed, or otherwise raised in the center - I think that would make them easier to press. - Basically 100% plastic - This isn't necessarily a con, but it doesn't feel as high quality as some of the premium mice that employ metal for certain parts. The surface around the side key pad appears to have a metallic veneer, but I believe that is also plastic. - Tool required for key pad adjustment - The mouse comes with a small 'hex' style driver which can be used to turn a screw on the bottom of the mouse, and thus adjust the key pad position. This tool is likely to get lost/misplaced by perhaps most people, meaning if you want to adjust it later you might find yourself rummaging through drawers or tool boxes to find the correct tool. Something like a knob, or spring-loaded locking tab, or wide flat-head style screw that can be adjusted with a coin, or even if the wrench is stowed on the mouse itself (like it is with my RAT 7) would all have been more convenient.

Overall Review: I won't include it with the 'Cons' because I don't know if it was isolated to my situation, but I could not get the firmware to update. The mouse works fine otherwise, but according to the software there is a new version of the firmware available but I am unable to install it. When I try to install the firmware it stops and says that there is no mouse detected and cancels itself. The real annoying part is that the software then acts like the mouse isn't plugged in until I unplug it and plug it back in. I have tried various USB ports, tried disabling the firewall, in addition to a few other things recommended by Corsair but I have yet to get the firmware to update. But as I said, the mouse works find so long as I don't try to update it so I'm okay with using it as-is. Overall I'm pleased with this mouse. It looks GREAT and feels comfortable. The software is easy to use and seems to function as intended (I've read a lot of complaints about the software but it seems Corsair has fixed many of those issues?). If you want a mouse with a key pad on the side like this one has then this one should be a strong contender. My only hesitation at that point might be the lack of physical customization options. You'll need to be comfortable with the weight and the palm size as those things can't be adjusted. Give it a look!

Pros: 4 Programmable RGB Lighting Zones Every button is programmable Buttons can be programed to macros or keystrokes Adjustable Side Button Panel

Cons: Side Buttons Easily and Unintentionally Pressed

Overall Review: The Corsair Gaming SCIMITAR RGB MOBA/MMO Gaming Mouse hits the sweet spot of not being too light or too heavy. It also contours well to my average sized hands. The finish on the mouse is smooth but it does not become slippery after long periods of use. The mouse has four programmable RGB zones that can be set to emit colors in unison or as separate independent zones. Every button on the mouse can be programmed to single keystrokes or multiple keystroke macros. The 12 buttons on the side are on a slider that can be adjusted forward or back depending on the hands position. However, to move this button slider you must use an allen wrench which Corsair does include. I first tried using this mouse with my work laptop running Windows 7 Pro on an Intel i7 platform. Windows required a reboot after installing the Windows version of the drivers for this mouse. After rebooting, I installed the Corsair Utility Engine (CUE) Software. Once installed, it prompted to update the firmware of the mouse. The automatic update to the mouse firmware failed, so I tried to force server firmware update and that also failed. I was unable to complete a manual update to the firmware as I was unable to locate any firmware on Corsair’s website. After giving up on trying to update the mouse firmware, I used CUE to program different lighting effects for each of the 4 RGB zones. I then programed commands that I use when logging into Linux for several of the side buttons. It was helpful being able to press a button in SSH and having long commands auto fill. However, I ultimately disabled these keystrokes from the side buttons as I found myself accidentally pressing these buttons when unwanted. I then took the mouse home to my Windows 10 Pro desktop on a AMD APU platform. CUE was able to automatically update the firmware without issue. However, this cleared the previously saved configuration back to defaults on the mouse. The mouse and CUE software support multiple profiles that can be used to configure different macros depending on the application or game you are running. However, I found myself using the programmable buttons more often for repetitive tasks to increase my productivity instead of games.

Pros: The mouse itself is made of solid plastic and aluminum throughout, nothing notable here. It feels like every other mouse I've held. It's sturdy -- it doesn't rattle, there's no loose components, and I'm certainly not worried about breaking anything even during intense gaming sessions. The wheel scrolls easily, with a soft tick between each scroll. Some mice require strong pressure for the wheel click, fortunately this is not the case for the Scimitar, as the wheel click is very easy pressed and depressed with minimal effort. This is a job well done for the physical construction of the mouse. The clicks themselves feel great. Light pressure, distinct, no feedback in the mouse itself (the mouse doesn't 'shake' when you click), no rattling on press or depress for any of the clicks or buttons. As a bonus, the cord itself is braided. It bends and twists with ease very little rigidity. Moving on to the software, there's a lot to take in. First and foremost, EVERY button on the mouse is 100% customizable. You can send any combination of keystroke or multiple keystrokes, along with codable macros. I'm also glad to see the DPI buttons are also customizable. The mouse has FIVE LEDs: The wheel, the logo, the keypad, the front, and the keypad keys themselves. Of those, all are totally customizable except the keypad light, which can only be set to solid colors. The choices for the other LEDs include cycling colors, pulse, and a rotating rainbow pattern. You can completely disable an LED by setting its color to black. All of these features are controlled via the Corsair Utility you need to install on your PC. It also manages firmware updates and other basic settings like your DPI and profiles. The 'Action Editor' allows you to record and edit macros, along with creating more complicated macros. It also controls functional buttons like video/audio/browser input. For all the lifters out there, the software also includes an adjustable lift height setting! Corsair managed to include everything you might need into the software suite, so I'm glad to say it exceeded my expectations. All in all, this is one of the best mice I have ever used, period. It blows all other MMO mice out of the water. Corsair left (almost) no stones unturned with the Scimitar, giving the user every possible way to customize and alter the experience to their liking.

Cons: No weights included. This is an MMO mouse, so it's not "designed" to play twitch shooters or other action games, so the weights are unnecessary to certain extent. On a premium product like this, it's expected though. If you're picky about mouse weight then you'll need to physically test the mouse first before you can decide if it's right for you. The colors of the keypad light are tied exclusively to your DPI setting, which means it can only be changed to 5 solid colors, based on your customizable DPI. If that is problematic for you, the LED can be disabled entirely. I should note the backlight of the keypad keys themselves is separate, and customizable.

Overall Review: This mouse is best suited for palm or hybrid grips. Claw grip would probably be sufficient, if you really wanted an MMO mouse. I wouldn't recommend it at all for fingertip grips. The mouse is slightly heavier than other similar mice, plus the thumb keypad makes it harder to grip. So the way you hold the mouse will drastically impact your ability to maneuver it. This mouse is LARGE and HEAVY -- shop carefully!

Pros: This mouse is made with quality in mind. Quality features include mechanical buttons, a braided cable, sturdy construction, rubberized textured grip and wheel, 12,000 DPI optical sensor, and wide smooth gliding feet. We don’t really expect less from a product by Corsair. But what makes this mouse unique? This mouse has a twelve button keypad that rests under your thumb. The keypad is adjustable (it slides) on the horizontal axis to accommodate people’s hand (thumb) sizes and sports 12 mechanical buttons for that nice clicky feel. The numbers are lit and are organized in four columns of 3 buttons, two columns which are textured so you can feel where your thumb is resting. These are the buttons you would program for use in games like World of Warcraft to execute and combine multiple in-game maneuvers. For example, press the button #12 to execute: [Target closest enemy; Cast(spell); Cast(spell); Cast(spell); Say “You be dead!”; Emote(dance); Equip Item 12(flowers).] All that can be done in one button press. You can make some really long maneuvers or chain shorter ones together depending on the circumstances. I played WoW with the official and programmable World of Warcraft mouse for a long time. Needless to say, while it was a benefit to use, I do like this Corsair mouse more. Just as important as the hardware of this mouse is the quality of the software. I like the layout of the Corsair Utility Engine. It’s pretty straight forward, and organized. Here you can program macros, keystrokes, mouse button presses, and especially neat, timer countdowns. For example, if you used button #12 to execute the above mentioned macro, you can also have the LED lights on the mouse change colors or flash a certain color, play an audio file (like a recording of your own voice saying “Starting flower power!” and then after 5 seconds of the button press, play another audio file clip from the song Another One Bites the Dust by Queen. This is just a simple example of what you can do. The possibilities are nearly endless. You can create game profiles and send them to your friends. You can change your curser’s tracking DPI on the fly (great for shooters) and have its current setting displayed by the color of one of the LED zones.

Cons: My fat, wandering, numb thumb. If you are accustomed to reading in Braile, you may have no problems with the thumb pad. I on the other hand, am having issues distinguishing what buttons my thumb is pressing. My thumb pretty much covers the entire pad of 12 buttons. They are small buttons. Corsair tried to texturize some of the buttons to help guide your thumb placement but I guess as a working man, my callouses prevent me from being able to feel the tiny little textured grooves. I would be perfectly happy if the buttons 4, 5, & 6 were removed leaving an open channel. I could then feel the edges of the remaining columns of buttons and the big empty channel itself, providing a bit more obvious tactile feedback of button location. I just slid the button pad all the way forward and am utilizing buttons 7-12. I also have a habit of tapping the side of the mouse with my thumb, and gripping the mouse like an Osprey gripping a salmon. This causes me to accidently press these previously nonexistent thumb buttons. This may not be a con of the mouse as much as it is a con of my habits. While a minor issue, I don’t like how far the USB plug sticks out. I plug the mouse into the right side of my keyboard and the plug gets in the way of my mouse movement.

Overall Review: The reason to buy this mouse comes down to three things. Number one: It allows you to execute custom macros, keystrokes, and game and program functions with the press of your thumb. Number two: It is a quality built mouse, sporting a super high DPI sensor, braided cable, mechanical buttons, and other features found only on high quality mice. Number three: It just looks cool. The reasons not to buy this mouse: You don’t want 17 buttons in your right hand; you don’t want to spend eighty bucks on a mouse; you don’t want to draw attention to your computer desk (though you can turn off all lighting); you are a left handed mouse user; or you don’t own a computer. The overall weight is nice, and there are no gimmicky add on weights (+/- 12 grams of weight is NOT going to make you a better gamer no matter how superman like you believe your sensitivity and reflexes to be). The braided cable is not so tight or thick as to interfere with movement. It also tracks and slides very smoothly over the Corsair gaming mouse pad I have. I don’t even use the included allen wrench to loosen and tighten the sliding thumb pad, with a little effort it will still slide and hold its place. Like it seems with all their products, this is a good, high quality mouse by Corsair. With all of the customizable LED lighting zones and sports car like black and yellow colors, it definitely offers bragging rights to its owner. Compared to other programmable mice, I really liked the way that the software was laid out and the many, many options it offers for optimizing your every gaming action. Combined with the program AutoHotKey, there is nothing on your computer that you can’t do through the buttons on this mouse. Concerning the few things about this mouse that I think could be improved, understand that those findings are of a personal opinion, based on my own style, setup, and habits, and may not bother you at all, or may even be bonuses to some. I would recommend considering this mouse for purchase if you are in the market for such a peripheral. This mouse sets a pretty high standard for future mice. It is not your father’s mouse, but it is a solid representation of what he may have envisioned future mice may be like.
