Customer Ratings & Reviews

I purchased the RVU Mercury because Razer supposedly fixed issues with this version. I can confirm this is true. Mouse 1 / Mouse 2 clicks are MUCH improved, the PTFE feet are thicker, and the side buttons are vastly improved. What I liked: Good coating, very grippy. Mouse 1 / Mouse 2 clicks are very responsive for optical switches. The scroll wheel is fine. It does make a little noise when you scroll up and this happened on both of my copies of this mouse. I had no LOD / tracking issues. I had no wireless issues. Razer Synapse software is fine and did what it was supposed to do. What I didn't like: This is an ambi mouse and using it for long periods of time hurt my wrist and elbow. I also didn't care for the pattern on the rubberized side grips. I returned it due to the grip issues. The quality of the mouse is great and the QC improvements are substantial.

very well connected and instant, it’s super light and makes my shots more accurate and it feels really sturdy in build quality. when you hold it it feels premium but when you lift it it feels cheap meaning it’s a premium lightweight mouse. side buttons are a bit tricky to press but i got used to it within a week or 2. very nice product i can’t lie. A way better upgrade over my Logitech G903

I’ve never even really been a pink girl but I absolutely love this mouse. The ergonomics of it is perfect as well, so comfortable. I like the ability to be wired or wireless!

Great mouse for gaming and everyday use. I love how lightweight the mouse is and it also takes up less space due to it being wireless. The charging dock is also a great addition as it makes charging the mouse easy and adds a bit of RGB lighting to your desk.

Interesting shape design on this mouse. While I prefer the feel of the G pro from logitech, I still recognize the excellent build quality here. Many like to bash Razer products, I am not one of those people. The charging dock was a nice extra.

After using a razer basilisk for about 4 years I decided to get a wireless and lighter mouse and I am very happy with my purchase. If you don’t want it to be wireless the cord for the charging dock doubles as a wired connection

I've been using this mouse for a couple months now, and it has been great. I switched from a wired mouse for gaming and I highly recommend this mouse. I love the dock it comes with too, it makes it super easy to keep it charged and store it between use.

It's Smooth, Super Smooth, for sure when I upgraded to this I had to get used to it, but I love it because it's wireless and If it dies I can go back to USB and charge it while I'm using it, then switch back to wireless whenever Its ready or charged enough.

I bought this to replace my Corsair m65 RGB pro and I was blown away at how much better this one is. Modern Warfare plays like a completely new game, my shots are so accurate now and it killed the lagginess movement that the game had before. I see how I was loosing many of the gun battles I was previously. I was intending on looking at the balisk Elite but they were out of stock and I couldn’t go in to see how it feels in the hand. They have all the Same sensor/wireless technology. But after using this, I don’t think I even care anymore. I was also blown away at how light this mouse is. I know I sound like a Razer employee, but I can promise you if you are on a mouse like I was and get this you will see what I’m talking about!!!

Hands down one of the best mouse out there I still use this and I bought it 3 years go

a great mouse, I wish this version was still sold I prefer to have the 2 extra buttons on the right side for extra functionality. The new version comes without them.

This mouse is truly amazing. This mouse is very comfortable with its ambidextrous shape. This mouse is amazing for shooters due to its lightning fast latency and 74 gram weight. This mouse is great for claw grip and fingertip grip users. Palm grip is ok for people with smaller hands but not recommended for a mouse this size. This mouse also comes standard with 100% pure PTFE feet although you couldn't go wrong replacing them with corepads or hyperglides. If you're in the market for a high end lightweight wireless gaming mouse you should 100% consider the Viper Ultimate. If you want to try a lightweight wireless gaming mouse from other brands, I suggest you consider the Logitech G Pro Wireless/ G Pro X Superlight, Steelseries Aerox 3 Wireless, Glorious Model O Wireless,

Amazing mouse with amazing battery life. I can go countless hours using this before having to charge it. Easy setup and solid overall. Love that it’s wireless.

Great mouse with a solid ambidextrous feel. The wireless dock is very convenient, and it works well. Battery is good. It lasts about a couple days with RGB on. Clicks are very good, better than GProWireless, G305, and Aerox 3. It has also been the most stable mouse out of all of them. It has had less hiccups and micro stutters with no disconnects so far. It has programmable side buttons on both sides. Solid feel, lightweight, stock feet are also good. Software sucks as it stores data. It also sometimes does not recognize the dock so the dock reverts back to the stock Razer green light. Only time will tell with durability. So far, it is my favorite mouse.

The Razer Viper Ultimate is a great mouse for gaming. I bought mine when it was on sale for $60. For what you got, it's a great value. Wireless with a charging dock, high polling rates, and subtle lighting, adjustable via Razer Synapse.

Bought this as a set for my gf and she loves it! I own the Basilisk mouse and I noticed this one is a lot lighter with almost the same functions and comes with a dock!! Great response time and very comfortable as well.

I love this mouse. It's super light and glides with little resistance. The real star is the dock. It's easy to place on the charger thanks to the magnet, and the RGB interacts with video games.

Great mouse. Very light busy solid build, solid responsive button clicks, ambidextrous, pretty good battery life. Razer software can be a little clunky but all good after you get your configurations set.

I love it so far, I forget to charge it sometimes but it’s still never died on me, I love the color, haven’t had any problems, doesn’t lag like other wireless mouses I’ve tried, would but again

Love this mouse it’s nice to have something wireless and move around freely on my mouse pad and the side buttons are great for gaming
