Hold Infinity in the Palm of Your Hand
With adjustable length, back-tilt and 2 different types of interchangeable side panels, the Razer Ouroboros gaming mouse ensures a comfortable shape for all grip types and hand shapes and sizes. It features gaming-grade wireless technology and 8200dpi 4G laser sensor to ensure outstanding performance. It also features a dedicated trigger button for dpi clutch functions.

Fully Customisable Ambidextrous Ergonomics
From an adjustable arched palm rest, to a retractable back, as well as four interchangeable side panels, the Razer Ouroboros is fully customisable to your personal needs. It fits perfectly with any hand length, shape and grip-style – maximise your comfort and reduce fatigue over extended play.

8200dpi 4G Laser Sensor
The Razer Ouroboros is outfitted with a 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.

Dual Gaming-grade Wired/Wireless Technology
Are you ready to take your gaming further than before, cord-free? As Razer is the pioneer of the world’s first gaming-grade wireless tech, you can be assured the Razer Ouroboros performs as well cordless as it does corded. With a 1 ms response rate, your command is executed first even if you and your opponent react at exactly the same time. When the battery depletes in the Razer Ouroboros, just plug in the USB cable so you can keep gaming while it recharges, for zero downtime.

Dedicated dpi Clutch-trigger
Stay on top of the competition and adapt to the situation with the Razer Ouroboros’ dedicated dpi clutch-trigger. Hold it down to temporarily increase or 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, and once the enemy has been dispatched with precision, release the clutch to return to your usual lightning fast assault mode.

Powered by a Single AA battery
Game for longer cordless when the Razer Ouroboros is conveniently powered by a single AA battery with up to 12 hours of continuous gaming. The supplied NiMH battery is rechargeable, so you can plug in the USB cord or place it on the dock to get it back up to full juice when depleted. Or, just hot-swap with any ordinary AA alkaline battery so you can keep going wireless like a beast.

Razer Synapse Enabled
Enhance your Razer Ouroboros experience with Synapse, Razer’s hardware configurator with online cloud support. From sensitivity to lift-off tracking to surface calibration, you’ll be able to customise every detail. Better still, this data is saved in the cloud, so you can play your way wherever you are. Razer Synapse keeps your Ouroboros in peak performance via automatic driver and firmware updates so you’ll be on top of your game, all the time.
