The RVU's smaller, more angular feet versus the Viper V2 Pro's more rounded, larger trio Michael Gariffo If you're a long-time user of the Viper family, the V2 Pro feels like its best evolution yet. It takes all of the high points of previous generations, sands off the few remaining rough edges, and leaves a well-tuned, laser-focused tool for aiming. Forget everything you've ever known about Razer gaming mice - there's no RGB here. While Chroma fans may be disappointed, I'm more than happy to sacrifice a few LEDs for the sake of such a battery increase. Everything about the Razer Viper V2 Pro has been streamlined for performance, and nowhere is that more visible than in the feature list. All three of those models mentioned are great mice for the right user, but that user is not one that prioritizes low weight over everything else. It's this exact demographic of gamer that Razer designed the Viper V2 Pro for. Side note: There are cleverly-hidden holes beneath the label and feet. If you'd like to see them, visit BeardedBob's YouTube video on his efforts to make the V2 Pro even lighter. His channel is also a great resource on mouse modding in general.

Each time the button is pressed, the PPP on the mouse changes—illustrated by an LED light near the mouse’s scroll wheel which changes from green, to blue, to teal, to yellow. The mouse starts to float as the green energy causes parts of it to disintegrate, revealing a newer, lighter form underneath.

We've added a link to the newly-reviewed Logitech G PRO X SUPERLIGHT in the Sensor Specifications of this review. We previously incorrectly stated that this mouse works on glass when, in fact, it doesn't. The review has been updated to reflect this change. A lightning-fast bolt of green electrical energy surges into the Razer Viper V2 Pro, supercharging it. We've added a comparison to the recently reviewed Razer Viper V3 Pro in the Comfort of Use section of this review. Finally, a power tab allows you to tweak wireless power-saving and make the mouse sleep after being idle for anywhere between one and 15 minutes. There’s also a low-power mode that will enter such mode after the battery percentage hits whatever number you set. Bottom Line

EU Declaration of Conformity for Abyssus Lite & Goliathus Mobile Construct Ed. Bundle (RZ83-0273).pdf I compared Logitech's G303 shroud edition to a sports car in my review of it. In its case, the analogy pointed to its shape being less-than-ideal for comfort, but excellent for accuracy. The comparison might be even more apt for the V2 Pro. But, instead of sacrificing comfort for accuracy, you're sacrificing a few features from the previous generation for reduced weight. We cut to an extreme close up of the sensor once again, as the mouse hovers with a red laser pointing towards the mouse mat. A slider appears parallel to the laser and starts adjusting up and down, highlighting how customizable the sensor is. We've converted this review to Test Bench 1.5. This update adds a new Main Button test group, which provides button actuation data and switch information. We've also made minor changes to how we calculate the Office usage score.
