If there’s a peripheral company known for being ‘all gaming, all the time’, it’s Razer. With thirty-five offerings spanning ten families, Razer has a bit of something for everyone. Today we’re taking a look at the Razer Viper Mini, an Ultra-Lightweight Design that features Razer Optical Mouse Switches and Razer Chroma RGB Underglow, Razer’s “leanest and lightest” gaming mouse for only $39.99.

The Razer Viper Family

The Razer Viper Mini ultra light mouse is the most compact sibling of the four-model Viper family gaming mice, coming in 8g lighter than the standard Viper and 13g lighter than the wireless Viper Ultimate, which is available in white and pink as well as a Cyberpunk 2077-themed colorway in addition to Razer’s signature black. Lastly, Razer offers the Viper 8KHz that features a higher polling rate as its name implies.

Razer Viper Mini Wired Gaming Mouse Versions and Colors

The Razer Viper Mini

The Razer Viper Mini we’re reviewing today comes in all black and shares its overall shape, button configuration, and Razer’s in-house optical switches with a claimed 0.2ms response time and 50 million click reliability with the larger Viper and Viper Ultimate. The Viper Mini also shares Razer’s Speedflex Cable with the Viper and uniquely features Razer’s Chroma RGB Underglow, providing a classy rear surface illumination along with the RGB illumination of the Razer logo on the back of the mouse.

The Package

The Build

With its ultralight construction and diminutive stature, the Viper Mini has been optimized for claw and fingertip grips. The matte texture provides just the right amount of purchase for minimal fingertip grips and is also used on the top of the DPI selector situated behind the mouse wheel and the thumb buttons.

Razer tastefully used a glossy plastic finish to outline the forward and back thumb buttons, mouse wheel, and to backstrap the main triggers giving the Viper Mini a bit of contrast, resulting in an overall presentation that is classy without coming across as too simple or boring. It features 6 programmable buttons. It also has on board memory profile to access your custom DPI settings without the need for software installed once you have the profiles saved with Razer Synapse 3.

On the bottom of the mouse, the large 100% PTFE mouse feet stand out alongside the 8500 dpi optical sensor. It should be noted in Razer’s favor here that these are welcomingly on the larger side for such a svelte mouse and show that the Viper Mini is built to last.

The Switches

Razer Viper Mini Wired Gaming Mouse Switches

Razer is using their infrared optical mouse switches in the Viper Mini, which are claimed to have an industry-leading response time of 0.2ms and to remove the need for debounce delay found in traditional switches that rely on physical contact. We found Razer Viper Mini to have very crisp actions on the main triggers, which while requiring ever so slightly more force to actuate, did indeed result in fewer unintended clicks in-game and out.

As is typical of retail mouse packaging, the Razer Viper Mini comes in a small box with the mouse and a small booklet. The Speedflex cable comes with a convenient rubber tie to keep the flexible, low-friction wire neat, and Razer’s Speedflex cabling comes across as a smart balance of durability and flexibility, easily bending without impeding mouse movement. Razer has put their signature shade of green in the USB A plug as a final touch.
