Customer Ratings & Reviews

It’s light, it’s fast, it’s comfortable I can’t say anything negative about this mouse. I went from a basilisks to a viper and it’s just an amazing improvement.

Extremely light, long battery life and docking it when not in use makes it to where I never have to worry about it dying.

Light weight and great battery life. Side buttons on the right sometimes gets clicked accidently, but after a few uses, you'll adapt.

My favorite mouse that I have ever bought. So I have been playing pc games with the deathadder for the longest time. The deathadder is bigger and heavier than the viper so switching to viper was a big difference for me. The viper is light weight and just feels really good when holding. I felt that the clicks are very responsive as well. Definitely my go to Mouse for all my FPS games from now on. The quality definitely matches the price as it is one of the more expensive mice out there. Also, I like the rib customization for both the mouse and the dock.

I wasn’t expecting to love it, but man... Great battery life, super comfortable, and a super light weight. Best mouse I’ve used in years.

One of the best mice in the price range. It’s light and the razer optical switches in the mouse are very responsive. Little to no delay in gameplay.

Fantastic product! This is my first wireless gaming mouse. I used a RAT Cyborg 7 and a Razer Naga before and they were both pretty good but ended up constantly double-clicking after awhile. The wireless stand is super convenient and sits off to the side on my desk, and it's not very big at all. It's definitely not an eyesore or in the way. Battery life is excellent and the precision, comfort and durability seem super so far. I wish it were a little bit more affordable, but I would still highly recommend it!

This is a superrr good mouse! I have a G403 Hero and it is also very good so I didn't want to change but I also wanted wireless. Pulled the trigger to buy this and haven't regretted it at all. If you want a mouse that is light in weight than this is the one to buy. It's like a toy it is so light it practically has zero weight. But it also feels solid, its not creaking or making any plastic noises. The dock is great too, magnetic so just snaps to the charging portion. Battery life has been great so far and really doesn't take long to charge.

I bought it when it was discounted so i was already happy. Shipping was a bit annoying but it was because of my fault. I got the mouse and been using it for a couple of weeks and so far it has been really great. It dosent run of charge quick when you charge it to 100%, like hell i charge my every week. The touch to it feels nice especially the clicks there is no delay on it. Plus if want a gaming area and want it to look nice it comes with a portable charger that lits up the mouse when charging and make it look like if its floating.

So much customization and so far the performance has been amazing in games and the charging dock makes my desk look even cleaner, expensive though for a mouse

Bought as a gift for my son. He has had no problems with it. Has a good battery keeps a charge for a long time. he hasnt complained about anything yet.

First off, I will this mouse is on the expensive side, just like the G Pro ( G502 and G903 Hero as well), but I think this one is a bit better value seeing it includes with a charging dongle....with that set aside, this mouse is AWESOME! It amazes me how light this mouse is (wireless mind you), just blows my mind. Sensor is dead accurate, and the battery is very, very good. I own both this and the G Pro wireless and I can't choose which one I like best, but if you get one or the other, you will be satisfied...I just think you get a little more with this one.

So far this mouse feels great. I switch from the Logitech g502. The switch made a huge impact but took some getting used to. My last mouse was heavy even without anyweights, it's economic, and wired with more buttons. This mouse is wireless, lightweight, less buttons, and simetrical. The battery life is very good, I barely have to charge it (low rgb lighting off course) the lightweight feels very good. But the mouse has a lower frame so if u have bigger hands might not be so great but u can adjust.

Got this during BFCM for a great price to replace my Logitech G Pro, which was double-clicking after many years, and I love it. Functions great, isn’t too big for my small hands, and the charging dock works great. Don’t even need the adhesive on the bottom to pick the mouse up off the dock. The resistance on the scroll wheel does cause some fatigue when I’m scrolling thru my social media feed sometimes, but you can always change the settings to scroll more per wheel spin.

Great mouse! It is comfortable, easy to charge, and white! I would recommend it! The extra buttons on both sides are extremely useful.

Charges fast, USB dongle is incredibly compaft and overall mouse is very sleek. Takes everything you know and love about the Wired version and cuts the cord!

I highly recommend it! Battery life is amazing. The clicking is not annoying or loud, but rather satisfying. Amazing value and quality!

This is a great mouse with almost perfect weight. The white version looks amazing. Mine had a small defect with one the feet being slightly off center which made the mouse feel a little scratchy when sliding it around the mouse. I was easily able to fix this myself by repositioning it so I will not take a star off because otherwise I absolutely love this product. Having said that, such QC issues should not happen with a $150 mouse. I originally purchased the black version, but was not happy with the left click. Mine was heavy and had a totally different feel compared to the right, with a dull sounding click. I learned that this is a common problem with the Viper Ultimate, but in late 2020 Razer upgraded their switches to "Gen 2" in the Viper lineup. There are still plenty of older versions floating around with the "GEN 1" switches. My previous black one was one of them and it that one was baaaad. That one was immediately returned. ALL colored versions of this mouse (White, Pink, Cyberpunk) all debuted with GEN 2 switches so if you want Gen2s, then buying a colored version is the only sure way to get one. The black version has since been upgraded as well, but a lot of sellers are still selling old stock (which happened to me) so its a gamble to get Gen 2s. Overall, this is my favorite mouse I've ever owned. I'm coming from a Dethadder V2 and this is miles better for me due to its smaller size. I have medium sized hands (but on the smaller end of that) and the hump of the dethadder was just too tall for me. My aim improved quickly with this mouse. I use palm grip and find it very comfortable. And honestly wired mice just cant compare to wireless when the latency with today's technology is non-existent. I got mine on sale for $100 (with charging dock) and at that awesome price its totally worth the upgrade. Personally, I would wait for a sale before purchasing one of these because $150 is too much for a mouse in my opinion, but if you want the best, GET IT.

Lightweight and amazing build quality. Smooth movement and long battery life. Little to no lag between the mouse and the computer.

Sick mouse! love that it is wireless and very convenient charging dock that works right away and very comfortable to use!
