Its very lightweight, really fast, and comfortable for medium sized hand shapes. The charging dock is a great addition and worth the extra buck to the non docked version. The build is also very solid with little to no creaking with hard presses. The only complaint I can give are the side buttons as it’s very easy to accidentally hit with your ring or pinky, however, those buttons can be disabled via Razer Synapse. Overall, this is a very reliable mouse and for a mouse that’s 2 years old. I highly recommend picking up this mouse for its features and quality.

This mouse is incredible, and especially because of its charging dock. I was worried about switching to a wireless mouse, but with the charging dock all my concerns were put at ease. It's incredibly simple, easy, and convenient to charge this mouse, and it holds its charge for days, if not weeks, depending on usage. I also love how lightweight it is, and never want to go back to using my old, heavier Corsair M65. The customization options, from the lights to the four extra hardware buttons, are great, and allow you to set up the mouse depending on your use-case (I have the buttons set to back/forward, and the other set to adjusting the DPI). Heavily recommend this mouse, especially at the $60 price point I was able to purchase it for.

The mouse is amazing! Its super light and there really isnt noticeable input delay using the dongle. Though I do have to say the scroll wheel could be better. I say this because it feels really cheap. Another thing is that there are 4 side buttons (2 on each side) which i sometimes hit accidentally but its not a big issue. Regardless, The viper ultimate is incredibly, huge upgrade from my viper mini. My aim definitely increased on fps games and it’s extremely worth it for its price at the moment

Very nice and light wireless mouse. This is gaming ready. Loving the subtle design and LED. Doesn't look like it belongs to a kid. Nice clicks right and left. Good skates on the bottom. The charging stand is nice but not necessary. Maybe would have preferred a cost saving option without the charging stand. Can play wired or wireless. Battery literally lasts forever. As good as you can expect anyway. The cable that comes with the mouse is pretty decent. Not as good as coolermaster's MM710. (I love that mouse) A few cons for me. I don't like the navigation buttons on both sides, or the placement in general. Easy to make accidental clicks. Really has been a deal breaker on making this my main gaming mouse. Front micro USB could have been type C for the price and another negative...the price, but you know. Also, the center wheel leaves a lot to be desired. The spikey knobbies are not comfortable, and it is mushy feeling to roll, not clicky. It does have a slight click, but not much. And the roll amount seems too low. I would like the mouse shorter with more of a hump on the back, I would say this shape is more for finger tip grip. It is a small mouse light mouse.

The mouse is good quality, on the smaller size, and some may find the buttons a bit small. I really like the charging dock and is basically the sole reason I got this mouse. The weight is good and the build quality is good. It has Razer Chroma for the lights so it is easy to adjust the lights to whatever color you want.
