The Razer Viper V4 Pro is an all-round fantastic mouse, with stellar build quality, satisfying clicks, and a nicely tactile scroll wheel. It also balances top-tier performance and a light weight with a surprising amount of juice.

The Razer Viper V4 Pro is the nicest mouse I've ever used. That's a bold way to begin, but I'm confident enough in the assessment to lead with it.
'Nicest' is also a pretty bland descriptor for what is essentially a flawless mouse, but that's intentional too. The recently released Logitech G Pro X2 Superstrike offers something very new and very exciting with its analogue haptic-inductive clicks, but we're not getting anything quite so viscerally exciting here. Instead, we're getting all-around traditional improvements that have me doing my best Michael Rosen impression .
The Viper V4 Pro has received a bunch of upgrades that make it the most performant mainstream mouse on the market today, but it's everything else about it that really impresses me. By this I mean the general build quality and overall value offering.
It might seem strange to talk about the "value offering" of a $160 mouse, but we're really dealing with the tippity top of the top end, here, and you're getting an amazing overall rodential experience (a technical term, I assure you) even for this price. Where Logitech's Superstrike ostensibly justifies its $180 price tag by offering snazzy new analogue click tech, Razer's Viper V4 Pro instead offers a flawless traditional clicking experience.
(Image credit: Future) You might assume the Viper V4 Pro to be relatively heavy to keep everything so sturdy and tactile, but you'd be wrong. The white version I've been testing weighs just 50 g, and an extra gram gets shaved off if you opt for the black version. That's well within 'ultralight' territory, and a good 20 g lighter than its predecessor, the Viper V3 Pro , and a few grams lighter than the DeathAdder V4 Pro .
It's kept the same shape as the V3 Pro, and here you're getting a pretty safe ambidextrous design. I tend to think of it as Razer's version of Logitech's safe G Pro/Superlight shape. Though the Viper is a little shallower and has the staple Razer flair to the edges of the left and right mouse buttons.
