Razer Viper Ultimate is a great ambidextrous, wireless mouse with a super-lightweight design that makes me want to ditch my heavier mice. The Viper Ultimate relies on Razer's software suite for all its customization, including Razer Synapse to change its settings and Razer Chroma to customize its lighting. It's an amazing FPS gaming mouse, while the Glorious Model D is an excellent choice for ultra-light gaming.
This rundown provides our analysis on 8 third-party reviews. The sentiment scores, summaries, and key takeaways that we select are based on these reviews and may differ from the original publication.

, albeit somewhat impractical, mechanical improvement under the hood. The Viper Ultimate uses Razer's new Focus+ optical sensor, which bumps the maximum sensor setting to whopping 20,000 dots per inch. Razer's other new high-end wireless mouse, the Basilisk Ultimate, is sold both with and without a wireless charging dock.

The Razer Viper Ultimate Wireless is great for office use. It feels very well-made, is remarkably comfortable, and has an ambidextrous design with buttons on both sides. Its dedicated USB receiver also works as a charging dock, with RGB lighting that changes colors to let you know its battery level. It offers multiple customizable buttons, with two side buttons on each side.

Reviewers from techradar have found the following[***]:
The Razer Viper Ultimate is an exemplary wireless mouse that excels in visual appeal. It's lightweight, yet somehow it still feels like a tank – albeit amazingly light. Its tracking speed comes boasting 650 inches per second, which is also lightning high so that the mouse can keep up with your movements on-screen. Most praise should be heaped upon its Razer Focus+ Optical Sensor, which can also be found in the bigger, more customizable Basilisk Ultimate.

The Razer Viper Ultimate's wireless performance and battery life are the biggest reasons to invest in this mouse. The mouse's included dock also merits a mention, as it can spruce up a drab desktop. It's worth noting that the Viper Ultimate makes use of a high-grade optical sensor.

Reviewers from tomshardware have found the following[***]:
The Razer Viper Ultimate uses the same optical switches found in the pricier Basilisk Ultimate. The Viper Ultimate's clicks had a more defined snap, perhaps due to its lighter build. Razer claims the battery can last up to 70 hours with lighting disabled. Some gamers will miss the ability to downshift in-game at a moment's notice.

The Razer Viper Ultimate is the first gaming mouse to own Razer’s new optical sensor, the Focus+.
