Razer Viper Ultimate Overview
The Razer Viper Ultimate is what I would call a normal-sized mouse. We’ve seen so many wireless mice that are small to cut down on weight, but I’m glad Razer has gone with a normal size here. The mouse has an all-back design and you can tell it is made for performance, not show.
For those wondering about actual size the official dimensions are 126.73 mm x 57.6 mm x 37.81 mm (LxWxH). The mouse is slightly more low-profile than the Glorious Model O and just slightly shorter. The mouse has an ambidextrous design, which will work well for both claw and fingertip grips.
At the top of the mouse you have two main buttons and a scroll wheel which is wrapped in rubber. The two main buttons make use of Razer’s own optical mouse switches. These are very much like the optical key switches we saw on their Huntsman Elite Gaming Keyboard. The switches have an industry-leading response time of 0.2 milliseconds. The top part of the mouse is mainly made of plastic, but it does not feel cheap by any means. On the front of the mouse you will find a small microUSB connection which allows you to use the mouse wired and charge it when you don’t have access to the dock.
On the left side of the mouse you’ll find two smaller buttons as well as a rubberized mouse grip, which is very comfortable. One the opposite side you have the exact same thing, so this mouse is truly ambidextrous. With rubber being used on both sides of the mouse it is pretty impressive that it is only 74g.
Flipping the mouse over to the bottom there are four PTFE mouse feet. At the center is Razer’s Focus+ optical sensor. It is a 20,000 DPI sensor with a tracking speed of 650 IPS, and a 99.6% resolution accuracy. Right below the sensor are two contact points, which are used to charge the mouse. To the right is an on/off switch and a DPI switch button.
There is a small compartment on the bottom of the mouse which houses the wireless receiver. This is a micro receiver so it won’t protrude out the back of your system or laptop that much.
The charging dock is also where you’ll place the USB receiver as it has a USB port built into it. It has two magnetic contact points that allow you to easily charge the mouse.
