Like the Naga Epic, the Ouroboros (Ancient Greek for "serpent chomping on its own tail") works both wirelessly and via cable. It may not have a hundred buttons under the thumb, but to attract gamers it instead relies on a customisable body and 8,200 dpi laser and optical sensors.


The sober body lights up, but only in certain spots (the scroll wheel and next to the side buttons). The hardish exterior doesn't feel quite as nice as, say, the Roccat Kone Pure's.

The biggest stand-out feature on the Ouroboros is that you can customise the body to fit the shape of your hand. You can make it up to 1.5 cm longer, from 12.5 cm to up to 14 cm, by sliding back the palm rest.

You can also raise the palm rest to make it higher by spinning the dial on the rear.

Two small side panels can also be added to either side of the mouse, held in place by magnets. We didn't find the thumb and pinkie grips really worth the trouble, as they change the way the mouse glides, making it not as smooth and quiet. We say stick with the other two.

Razer Ouroboros front

Like the Razer Taipan, the Ouroboros works equally well for righties and lefties because there's a set of three thumb buttons on both sides. These buttons can be assigned to your favourite commands, shortcuts and macros.

The buttons on the pinkie side are good for actions you don't use as often. Sadly, for most people button 3 will be too hard to click with a pinkie or ring finger.

There are two more buttons right below the (ratchet-style only) scroll wheel, for a total of eleven buttons. People tend to use these for adjusting the resolution on the fly (anywhere from 100 to 8,200 dpi), but you can assign them to whatever you want in the driver.

The driver itself is easy to use. It's where you go to choose the button commands, save configurations as profiles and assign profiles to specific games and programmes. You can quickly tell which profile is active by looking at the intensity of the green diodes. Unfortunately, the diodes don't change colour, so it's harder to see which one it is when changing profiles on the fly.

Like the Naga Epic, the Ouroboros works both wirelessly and via cable.

Razer Ouroboros wireless

When it's wireless, the charging station doubles as an interface with the computer. The mouse is powered with one rechargeable AAA battery (included).

Razer Ouroboros battery level

Razer put a battery indicator at the top of the mouse in the form of three short, horizontal lines that light up. Or you can go into the driver to see how much battery is left as a percentage.

To connect the Ouroboros via cable, you just unplug the USB cable from the charging station and plug it into the front of the mouse. That way the battery recharges while you use the mouse. Or you can take the battery out and reduce the weight from 120 to 105 grammes.

Every time you switch from wireless to wired, it takes the driver a couple of seconds to detect it, so you'll have a moment of latency. Best not switch it up mid-game.

All in all, the Ouroboros has pretty much everything you could want out of a mouse. We would have preferred a smooth scroll wheel—it may not come in particularly handy for video games, but it's much more enjoyable when web browsing.


With 1000 Hz polling, the Ouroboros can handle both standard tasks (productivity, web browsing, etc.) and tasks that demand more precision (gaming, graphic design, etc.). Unfortunately, you can only reach 1000 Hz when the mouse is connected via USB. Using it wirelessly the poll rate drops to 750 Hz.

Razer Ouroboros speed
A gaming mouse requires a sensor capable of handling speeds of up to 3 metres per second.
The Ouroboros detects twice that speed!

At 1000 Hz, the Ouroboros requires less processing power (22%) than many competing mice, which tend to range from 30% to 40%. But if you still need to free up more power you can always drop the polling rate to 500 Hz in the driver.
Online storing for profiles and configurations
Configuring the buttons on a mouse can be a tedious task, and it would be nice not to have to redo it all every time you get a new computer or operating system. That's why Razer offers Synapse 2.0.

When you download Synapse 2.0 from Razer's website, you're asked to create an account, on which your mouse settings will be saved online. That way, the next time you reinstall or upgrade your OS, you can import all your mouse settings, profiles and macros straight back to your Ouroboros. Several different Razer mice can be synced to the same account.


  • Ultra-precise sensor
  • Buttons for adjusting sensor resolution on the fly
  • Config profiles save to an online account (transferrable to other PCs and OSs)
  • Unlimited number of profiles
  • Extensive driver software
  • Customisable body (width, length, height to fit the shape of your hand)
  • Three thumb buttons on either side
  • Works wirelessly or via cable


  • Exterior coating a bit hard
  • Polling rate drops from 1000 Hz to 750 Hz when wireless
  • No smooth scrolling
  • Price


The Razer Ouroboros is ultra-precise, practical and ambidextrous, and works wirelessly or via USB cable, but its coolest feature is really the customisable body. Gamers and DIY lovers may have met their perfect mouse.
