Plus, the mouse only weighs about 74g. That's amazingly lightweight, which makes it perfect for competitive gaming and esports. Your reactions will actually improve just because of how smoothly the mouse flows in your hands. It also uses a 20,000 DPI otpical sensor that you can adjust yourself.

The Viper has an ambidextrous design so it's good for both right and left handed gamers. There are programmable buttons on either side of the mouse. You can use the Razer Synapse software to reconfigure all the buttons and create complex macro functions.

The mouse's battery lasts for up to 70 hours. You'll only have to charge it about once a week. When you do go to charge it, use the included charging dock.
