The Razer Ouroboros employs a cutting-edge 8200 dpi 4G laser sensor for incredible precision that delivers amazing gaming control. Powered by a single rechargeable AA battery, the Ouroboros is capable of at least 12 hours of continuous gaming. It is also ambidextrous. It lets players configure various ergonomics components – from its adjustable arched palm rest to its retractable back panel and interchangeable side grips – to get the best fit for their own hands, regardless of shape, size, or grip style. This ensures users can game for hours on end in complete comfort while minimizing fatigue. Optimizing the balance between quality, durability, and customization, the Razer Ouroboros is the most advanced gaming mouse you’ve ever seen.

  • newegg Fully Customizable Ambidextrous Ergonomics The Razer Ouroboros features fully customizable ergonomics, allowing users to configure the mouse to comfortably fit their hands regardless of hand length, shape, or grip style. This mouse can be custom configured with an adjustable arched palm rest that allows a user to choose from various angles. It also features a retractable back panel that can be set to any one of three positions, as well as four interchangeable side panels.
  • newegg 8200dpi 4G Laser Sensor The Razer Ouroboros is outfitted with the most advanced and configurable sensor yet, the all-new 8200dpi 4G laser sensor. It tracks so precisely; you always hit targets exactly where you need to. It can also be calibrated to your specific surface, and has adjustable cut-off to lift-off tracking, empowering you with more control than ever.
  • newegg Gaming-Grade Wireless Technology with Dock With a 1ms response rate, your command is executed first – even if you and your opponent react at exactly the same time. The included charging dock also acts as the wireless transmitter. The button located at the front of the mouse syncs the dock with the Ouroboros.
  • newegg Dedicated DPI Clutch-Trigger Stay on top of the competition and adapt to the situation with the dedicated DPI clutch-trigger. Hold it down to temporarily increase/decrease the mouse’s DPI, so you can get the exact sensitivity you need for the moment in-game. For instance, when you switch to a sniper to take out a target far away, use the clutch to slow your DPI down; once the enemy has been dispatched with precision, release the clutch to return to your usual lightning fast-assault mode.
  • newegg ARM 32-bit Processor The Razer Ouroboros is outfitted with a 32-bit ARM processor, which means there’s a little computer onboard that is computing everything at an incredibly fast rate. The mouse is quite literally an extension of your hand: every movement you make, and every function on the mouse you execute, is delivered instantaneously.
  • newegg Synapse 2.0 Synapse 2.0 is not just a standard mouse configurator. It's packed with basic and advanced customizable features, so your Razer Ouroboros works exactly the way you want it to. No longer limited by a last-generation onboard device memory, Razer Synapse 2.0 brings the brain of the Razer Ouroboros to the cloud, expanding the number of storable profiles and configurations to infinite, and allows for longer, more complex macros.

1 out of 5 eggsflimsy material

Pros: 1. It looks really good.

Cons: Made out of flimsy material, making it unreliable.

Other Thoughts: So I bought this mouse because I had a R.A.T. 9, but I needed to replace it. I chose the Razer Ouroboros because it had the same kind of customization, and it packed in some really good specs. The mouse was great for the first few months, but the first thing I notice was that the right click button started to feel a lot less clicky the older the mouse got. It was very annoying to have the left click button have a very sharp and definitive click, while the right click be so weak. This made me want to really slam down my finger when gaming so I would really know that I was using that button when I wanted to.
The second thing that happened was that the adjustable palm rest came undone. When I tried to get the part slotted properly, I noticed that the mechanism was held by just some plastic. I had to bend the part back in place, which made it weaker. The same part kept coming undone the same way more and more frequently until the tiny hook that was holding it together just broke. So then my palm rest was just floppin around
I started to become very frustrated with this mouse the more and more I used it. The left click button eventually started acting like the right, with a very weak click.
When I investigated the "clicker buttons" all I could see was that the middle of each had become bent--caved inward just a little bit. I assume from the placement of my fingers and the warmth of my room.
Other than that, the wireless was fine, but I found myself more comfortable with the mouse wired.
So I am very unhappy with this mouse. I've switched back to my first gen deathadder which seems to work like new still.
I'm just very disappointed that I paid over a hundred dollars for a mouse that bit the dust within a year.
So do yourself a favor and don't go for fancy, just get a deathadder or similar.

5 out of 5 eggsExellent

Pros: Love the Razer Ouroboros. I was planning on buying a R.A.T. but changed my mind. Mouse is adjustable to my small hands. It also works well with the Synapse 2.0 software that Razer provides.

Cons: Was a little difficult for my computer to sense at first. Had to uninstall and re-install the software for it to sense the mouse.

1 out of 5 eggsTerrible support and a bricked device

Pros: Great for big hands, responsive

Cons: Short battery life, bricked receiver.

The wireless receiver came unplugged during gameplay and I contacted razer support. After waiting 2 days for a specialist I was told it needed a firmware update, something I had already tried.

I went through it again with the support rep & when it still didn't work I was told I would need to wait 5-10 business days for a replacement receiver & another 3-5 business days for shipping. This is utterly unacceptable in terms of product & support quality.
For half the price go with logitech I have never had a single issue with any logitech mouse I have ever purchased.

4 out of 5 eggsExpensive but well worth the price

Pros: Cool design
On the fly DPI change buttons
Ability to turn two side rests to buttons
Customization a plenty
Scroll wheel is satisfying
Easy to change from wireless to wired mouse
Easy to change palm rest and in multiple ways

Cons: Takes a moment to be used again when lifted up and put back down
The side rest/buttons are a little hard to push when active
Synapse 2.0 doesn't allow local saving of mouse set up.

Other Thoughts: While the price is a little steep for a gaming mouse, it's well worth the money. It comes in a really cool box that almost makes one think that it's for display purposes only, but to actually get it back in there, you need to reset all the physical settings on the mouse. At first it was hurting my hand but after adjusting the palm rest placement on the mouse and the palm rest itself, it feels a whole lot better. No more pain!

Overall it's a great mouse. If the price was below 80 dollars, it'd honestly be a steal.

3 out of 5 eggsIts okay...

Pros: -Cool looking.
-Wireless doesn't have lag from what I see.
-Decently light/can be heavy with battery.
-Okay customization.

Cons: -Way too expensive for what you get.
-Can't change colors like the Mamba or Naga Epic.
-Side buttons don't feel that great.
-Mouse wheel feels like it is mounted wrong.
-Left AND right mouse clicks start to squeak after 2 days of using it.
-The "thumb" buttons don't always register with synapse.
-Buttons under the mouse wheel feel like they don't last.
-Isn't easy to change the length fast/need screw driver.
-Awkward to hold all around.

Other Thoughts: I'm not writing this complaining about synapse because we all know its not a good program. I didn't have that much trouble with it but that doesn't mean it doesn't take up more processing power than it should.

I haven't even had the mouse a month and I'm done with it. Way too much money and its nothing special. I would rather have the Taipan but I've had 3 of those go wrong. Also have had the Imperator and it failed me. Overall I think I'm done with Razer as a whole unless they come out with something extremely great which they won't since they don't change anything cause they're too stubborn to listen to the comsumers.

3 out of 5 eggsNot worth the money

Pros: Looks great
Made by Tazor
Cool colors

Cons: After about 6 months of ownership, I'm not sure if the batteries are going bad or what but it randomly shuts off, even when the battery is full.

Sometimes the battery does not charge either.

You cannot adjust the mouse very much, as compared to a RAT mouse.

Sometimes the mouse will lag, and jump across the screen.

Other Thoughts: Cool mouse, but not worth the $150 price tag.

5 out of 5 eggsKing of the battlefield

Pros: This is a lovely mouse. Absolutely the best moues I've owned. I've loved it ever since the second I got my hands on it. I wouldn't recommend any other mouse over this one.

For starters, it's extremely comfortable and customizable - not as customizable as some mice, but enough for me. The adjustable palm rest is awesome and has a lot of adjustability. The exchangeable side grips are kind of a letdown, as there are only two pairs to choose from. Fortunately, the extended ones work great for me. It feels great in my hand and I never get that "cold feeling" from a shortage of blood in my hand or cramps – ever. It has really nice solid clicks, and just glides smoothly on my Razer Vespula mousepad. It’s performance is awesome and it’s extremely responsive. The idea of having 8200 DPI is just amazing, even if I don’t personally use 8200 DPI (3000-3500 for me personally). The dual sensors ensure that it has smooth tracking and precision movements. I noticed an immediate benefit when playing FPS games over my old Naga 2012 edition; the precision is just all there, and I’m loving every second of it - more headshots than ever before.

The wired/wireless mode is awesome. Wireless is very responsive with no lag thanks to a 1000Hz polling rate, and if you run out of battery juice, you can plug it straight into the PC and continue gaming. I absolutely love the dock – it works as the wireless station and the charging bay. It looks fantastic too and has an anti-slip bottom to prevent it from moving when you attach or detach the mouse from it. It will even charge your mouse while your PC is asleep (assuming your motherboard supports standby USB charging).

It looks absolutely lovely and has great attention to detail as well. Whenever people see it, they can hardly believe it’s even a mouse; they say it looks like a piece of art or some sort of transforming toy. Let me assure you that this is no toy – this mouse is a virtual weapon. I really can’t describe how awesome this mouse is. The weight is good, the build quality is good; it’s just all around perfect. The supplied USB cable is very long and has that quality braided sleeve to it.

Cons: Most of the cons I have to state about this mouse are towards Razer Synapse. Although it hasn’t given me too much trouble, there have been a few hiccups. The first one being somewhat occasional DPI settings being wrong – what I mean is that, sometimes when I wake my PC from sleep, the mouse sensitivity is really low. Restarting Synapse usually fixes this, or a reboot. It’s just a small bug out of the blue that doesn’t happen too often.

Also, when starting or rebooting PC, the mouse is hyper responsive for a minute, but always fixes itself. I can’t really call this a con, as this happens every time. The only thing I can assume why this happens is that the mouse has to wait for it to sync up with Synapse to get your proper user settings loaded. No big deal here.

The battery life isn’t the best, but decent considering all the mouse does. It has to update 1,000 times a second, with high DPI on 2 separate lasers, with LED lighting all around it, all while on wireless. It will last about 12 hours with heavy use. Expect to charge it nightly. On a positive note, the supplied battery (which is green too; a pretty nice “Razer” touch, not that you will ever see it) is still working like a champ, and showing no signs of wear, and I’ve had this mouse for 8 months now.

The left click started to squeak after 2 months or so of use. I have read that this is a pretty common issue with this mouse, and applying WD-40 to it can prevent and/or fix this issue. I just ignored it and it eventually went away on its own after a month or so.

The only other thing I can say is that for this being the cream of the crop Razer product, it’s kind of a bummer that it only has green LEDs. It works for me, as my PC theme is black and green, but for it being a flagship mouse, it really should me multi-colored.

As a side note not entirely related to the mouse, the mouse pad “optimizations” in Synapse actually do have an effect on the mouse; in my case, not a very good one. I use the “speed” side of my Vespula mousepad, and I set the mousepad optimization in Synapse to just that. Although the mousepad is excellent and very sturdy, it scratches and shows wear very easily – noticeable in the first few weeks of use. Because of this and this mouse’s superb sensitivity, when it glided over the scratches, the laser will pick them up and track incorrectly. Turning off the mousepad optimizations completely fixed this. DO NOT USE THE MOUSEPAD OPTIMIZATIONS.

Other Thoughts: I love having a powerful mouse that makes a powerful statement as well. It looks bold, performs like a boss, and shows I’m ready to jump into the battlefield with all guns loaded. I was a little weary about the price at first, but I can now see that it is worth every penny. The few flaws are mostly unrelated to the mouse itself and mostly towards Synapse, although Synapse has still treated me well.

I absolutely treasure this mouse and would buy it again, without hesitation. Now stop reading this review and buy it already!
