The Razer Viper Ultimate is an outstanding mouse for sure. It is lightweight and the connection feels just like a wired mouse. However, Razer has some quality control issues, especially with this mouse. I am on my 3rd RMA. The switches are just horribly inconsistent. It either creaks a lot or it feels "sticky" and less snappy. Only buy this mouse if you're feeling lucky.

Got it and used it for work and everything seemed perfect. Then finally got some time to use it for a 3rd person shooter game. That's when I noticed the right mouse button(right click) sometimes fails to register. Shooting games uses a lot of right click that's the default button for scope . Searched online if it's a known issue, I did find mentions of issues with right click but not quite similar with mine

Using the same shell as the Razer Viper (2019), making it wireless while making a few notable changes is what defines the Razer Viper Ultimate. It’s a great product overall – and I love the new scroll wheel. I think it’s a missed opportunity for the dock to not be a receiver.

Fantastic tactility and resistance on the scroll wheel rotation, Good wireless reception, no dropoff, Comes with removable SpeedFlex cable, Razer Synapse implementation with the dock is excellent, Still lightweight despite having a battery, Long-lasting battery life, Trophy-like stance while...

The wireless receiver dongle is a nuisance to be constantly plugged/unplugged from one PC to another, as the dock could’ve been another wireless receiver, “Proprietary” micro USB header, Hefty price premium for wireless functionality

Compare to my Logitech and razer manga, the viper is much better. It is lighter and more accurate, suitable for both right hand and left hand user.

I really enjoy the mouse I bought it mainly for video games such Fortnite. And I am really happy I got it, although I didn’t like that you can’t take the thumb buttons out and it comes in my way but overall I love a lot good job Razer keep up the good work!

The Razer Viper Ultimate offers up some premium tech packed into a featherlight, ultra-responsive chassis, and the result can often be a stunningly intuitive experience.

Impressively lightweight, Lightning fast click response and tracking, Subtle design

Expensive, Small number of programmable macro buttons, No option to add weight

Razer’s new Focus+ Optical Sensor puts the Viper Elite at the top of the wireless pile. Some of its buttons fail to live up to its hefty price tag, but its long battery life and elegant, ambidextrous design more than make up for it.

It's been just a few months since Razer announced its light-and-fast ambidextrous mouse, the Razer Viper, but the company already pushing a high-end wireless version to match. The Viper Ultimate ($149.99 with its wireless charging dock, $129.99 without) takes all the esports trappings and design choices of the original and affixes them to a wireless gaming mouse that, like all of Razer's wireless models, injects high-end features to justify a high-end price. The Viper Ultimate manages to cut the cord without any major compromises in its design, making it the best wireless esports mouse I've used yet. It's pricey for the full experience, but if you're resolute about both wireless connectivity and performance, it's worth it. It earns our Editors' Choice for wireless gaming mice. The Serpent by the…Wait, Where's the Tail? Like the original Viper, the Viper Ultimate is a high-end take on the seemingly standardized esports mouse. It, technically, has eight buttons—two main left/righ...

Razer's Viper Ultimate untethers and upgrades one of the best gaming mice a competitive esports player could ask for. It's a winner, but get the version with the charging dock.

Comfortable ambidextrous design; No-compromise RF wireless connection; Wireless charging is convenient and looks sharp

A bit expensive for the full package

Razer Viper Ultimate Wireless Gaming Mouse is almost the perfect wireless mouse... very close indeed!

It’s the smoothest mouse I’ve seen. 0 lag, 0 delay, 0 issues. Constant - 100% consistency in providing smooth connection. The connection to the whether ipad, mac, pc is just amazing, both wireless and wired. The wire is high quality too unlike the plastic ones. Also the packaging is fabulous with cool razer stickers. Razer synapse makes everything cool too but a little more RGB would have made it better. Anyways, still top notch and the best mouse in the world for gaming and general use. The connection and smoothness as well as response stands out the most to me.
