Pros: very high DPI, programmable buttons

Cons: until the update razer synapse was really clunkly Cannot change the color profiles like with the earlier generations.

Overall Review: Feels well built and if you are like me, with big hands, you will find this mouse perfect if you use a claw grip.

Pros: Extremely high DPI Very programmable with multiple profiles Easily conforms to fit your grip.

Cons: Only decent battery life. Says up to 12 hours. I have the DPI about in the middle, 3600-5000 most of the time, and I only get about 8 hours. I keep a second battery with me because I don't like using it wired. The software is kind of annoying.

Overall Review: I use this on my gaming computer at home, and on my work computer for the macros. It works really well for both. But the battery life could be a lot better and the software does not always sync my profiles between the two computers.

Pros: -19 programmable buttons including scroll wheel tilt -Shape is more comfortable (slightly wider where pinky grips) so my hand won't cramp -good drivers with unlimited number of profiles and ability to auto-swith to the appropriate one when you launch a .exe -ability to import profiles from cloud that you set up on other razer devices -side buttons are easier to push -you can change the color of all the lights and set patterns or have it fade through the color spectrum which looks cool -sturdy and long braided cord

Cons: -pretty expensive compared to some competitors -side buttons are easier to push. I list this as both a pro and a con because you can accidentally press them if you're used to gripping thumb on pad -shape of side keypad is a bit different, so I will have to re-learn muscle memory (the old one was like an oldschool nokia phone keypad and felt smoother but you had to push harder) - i feel like the side buttons could be a little closer together between rows or stick out a little bit less - there is no bump on the 5 and 11 buttons for tactile reference i'm nitpicking because I used that previous naga pretty extensively and really came to love and rely on the keypad for all genres of games, not just MMO

Overall Review: You can get a good mouse from other brand with a side keypad for half the price of this one, but I got this one mostly because the drivers are superior, don't limit the number of profiles, and I could use the 20+ profiles I had set up with my old naga which would have been a real hassle My previous Naga was 2013 or 2014 version and I replaced it because I wore out the middle mouse button and was unable to repair it

Pros: - very comfortable - very precise - on the fly dps adjustment - can use synapse to customize color and pattern

Cons: - mouse will randomly become unresponsive weather im in the middle of a game or browsing newegg or facebook. when this happens it does not matter what you click or push it will stay unresponsive until you physically unplug it from the usb port and plug it back it. note everything else still functions normally when this happens including keyboard, pc, headset, and mic.

Pros: the way my hand sits on the mouse is like no other and a huge plus with the thumb support. this has improved my FPS skill which I thought I had lost. It really is all in the mouse.

Cons: It doesn't make a grilled cheese for you.

Overall Review: If your looking for a mouse that fits your arch of your hand better then all the wide ones that most are designed after now then give this a try. the fit from my thumb to pinkie finger feels good unlike others that have cause my pinkie finger to twitch out. I am actually going to order a 2nd one just in case I ever have an issue.

Pros: - Chroma Lighting provides an amazing array of customization to match your rig - Solid build - Braided cable doesn't "push" my mouse to slide across my pad as traditional rubber cables do when they're taut - The slider clicker is very smooth and feels great to the touch. It doesn't require a whole lot of pressure to click, but you won't accidentally click it either while scrolling as I've noticed with other mice - Love the functionality of the rubber grips on the sides. However....

Cons: - Part of the rubber grip on the side is peeling off straight out of the box (nothing to get angry about and a little crazy glue can't fix, but a con just the same). I'd expect that for the price, this mouse should be flawless

Overall Review: Razor's reputation speaks for itself. However, I am not sure If I'd be ready to drop $70 for this mouse. I received it free as part of a newegg promotion with the purchase of a Razer Chroma keyboard that I just had to jump on. So far I am pleased with the quality.

Pros: Cool lighting, decent feel for gaming.

Cons: Beware something seems to be wacky with a lot of these... The sensor and/or firmware is wacked out, Cursor would stop moving and would take a few seconds to kick back in mid game, Mouse finally stopped working all together.

Overall Review: Sent the mouse in for RMA 2 weeks ago and still no exchange from Razer RMA dept... To bad I have loved other Razer products but this one has been a letdown.

Pros: The concave shaping of the side buttons is really helpful; makes them all easier to reach than on the previous Naga (I had the right-handed version). They have a much "clickier" feel, as well, which I also like. I like to use this mouse with a mouse wrist rest, since I prefer to move the mouse with just my fingers rather than the palm of my hand.

Cons: No cons; only problem I had with it was resolved (see below).

Overall Review: This mouse arrives with the mouse buttons switched (left-click is the right mouse button, right-click is the left mouse button). It is possible to switch the buttons, despite the fact that left-click will be greyed out as not editable in the Synapse 2.0 software. To get around this, you'll need to change the left-hand button to left-click first, then you'll be able to change the right-hand button to right-click. The easiest way to do this is just use a different mouse to change the settings. Hope that saves other people a lot of frustration; this drove me crazy for several weeks before I got it fixed. (I had switched the left and right mouse buttons in Windows Control Panel, but some games and Windows Remote Desktop don't pay attention to those settings, so it was not behaving consistently.)
