The best mouse I’ve ever owned.
So I bought this Razer 8k used/like new, and I didn’t know what to expect. I bought and returned multiple different mice before settling on this one, and after a couple of fails, I decided I’d go open box in case of more side buttons being unreachable or ergo shapes being uncomfortable, or whatever and having to return them. Anyway, I got this 8k for about $26. It arrived in resealed original packaging with no accessories or anything, which is fine at half price. It also came smelling like sanitized chemicals, and had tiny tannish food scraps or something in the rubberized side grip. A little rubbing alcohol and it was new again. After cleaning it, I used it for different things including web browsing, Android Studio, Blender, and Fortnite. The buttons have the greatest click I’ve ever felt, the scroll wheel is large and protrusive and has distinct notches as you roll it, which is made for FPS games like Fortnite, PUBG etc, for precise item selection, but would be annoying for some things which require smoother scrolling. The scroll click is easy and precise. . . the whole thing feels like a whole different level in feel and quality, from other mouse scroll wheels. I use the inside thumb buttons for jump and slide in Fortnite, and I disabled the left hand thumb buttons, which surprisingly, I don’t feel, when my third finger rests there. I had to get used to the low profile of the thumb buttons, but once I adjusted to them, they actually work very well. Ergonomically, I prefer a hump towards the rear of the mouse, but my hand adjusted to that too. The 8k feature is wasted on me, because most lower-middle end PCs can’t handle 8000 reports per second from the mouse, but the 1k setting is perfect. Everything from the PTFE skates to the Razer Focus+ sensor to the optical v2 switches is premium and frankly amazing for the price (which I paid half of.) Also, other than some of the $150ish Asus ROG mice, the Razer optical switch mice, like the Viper 8k, have hot-swappable switches, so if one of the top switches breaks, it’s about $10-15 a pair to replace em and they just clip into place. . . no soldering. So, I really love this mouse, and I can’t really recommend anything other than a Razer, after trying different mice. Its just different, unique and better. Apparently, from reviews I’ve seen, the other Razer mice have a smoother scroll wheel, for a less gamer specific, more universal functionality.

first razer product, and it’s an absolute winner
For transparency this is my first razer mouse, and only my 3rd mouse. fist was a cheap havit mouse that came with a bundle. second was a steelseries 600. Honestly I assumed I’d get this mouse and be underwhelmed.so far, it’s been about 2 weeks. this mouse is ultra light to me coming from a steelseries rival 600. the steelseries was slightly over 100 grams so it’s almost 30 gram difference. this weighing in at 74. I didn’t really expect it to affect my or even be noticeable. boy was I wrong. instantly lighter and the feet on this mouse glide so smoothly.very responsive and quick. thought I may have to turn down my dpi or sens due to how much lighter and smoother the razer is. However, from that heavier steelseries with weaker glide, to this much lighter exponentially better gliding 8k, it was seamless. adjusted extremely quickly.The shape is great feels great in my hand. did take me a minute to get used to as far as that goes simply because my last mouse was bulky and an unorthodox shape compared to most gaming mice. Now due to that there was some weird stress, and fatigue that presented in my forearm. again it adjusted quickly. after, at max, a couple 3-4 hour sessions it was gone. There are 4 total side buttons, but theres a caveat there I’ll touch on later.the wire on this is absolutely perfect. 0 drag, dont even notice it’s there until I look down. dont have to use my cord bungee either. I almost got the viper ult but knowing how this mouse feels, it would’ve been a waste of money to me.As great as this mouse is there are a couple trade offs and things I didnt know. these are not in number of importance.1) since this is ambidextrous, theres 4 total side buttons, one set on each side. Coming from a mouse with 3 side buttons and the way I had things mapped, I assumed I would be able to map all 4 buttons. wrong. the buttons are M4/M5 on each side. you have to choose if you are right or left handed in the app and that sets which side is being used and how they’re numbered. kind of a bummer here but this is a personal issue not necessarily reflective of razer. coming from more to less is situational. I would just like that extra personalization.2) The 8k polling rate. this provides an extremely smooth mouse movement. this may be different from person to person. maybe mouse pads make a huge difference I have a relatively cheap one atm. One issue I’ve run into is Apex legends WILL NOT run a polling rate over 2000 on a 144 hz monitor. or at least not on mine. rainbow six siege I can crank to 8k and no issues. so maybe its game/display/system dependent I dont have a way to test it.3) I’m a person who enjoys rgb and wish there was more. this is a non issue for most I’m sure, but this is about the only thing the steelseries had over this mouse was the customization options for rgb.4) the liftoff distance. this is the number one win for steelseries. they had a liftoff distance as low as .5 mm lift off distance which I absolutely loved. the lowest for this mouse is 2 mm. so lifting and lowering there is mouse jottering I’m not a fan of but overall not a big issue. big win for steelseries here.Barring any huge issues this is a mouse I would 100 percent recommend at time of this review. buy it, check it out. I doubt you’ll be disappointed!

Best mouse I’ve had for left handed.
I bought this mouse originally in 2021 for a gaming/office computer. I lost it in a move and tried both a Corsair and Logitech ambidextrous mouse before repurchasing this one from Best Buy locally a few days ago.It’s the software. The Corsair mouse requires you to enter Left Hand mode which swaps mouse button 1 and 2 to enable the right side mouse buttons. I tried to reassign the 1 and 2 keys and it caused a huge problem resulting in a blue screen crash. The Logitech has the right side buttons assigned to keystrokes you have to undo.But the Viper has my beautiful right side buttons as keys 4/5 just as they are on the left. It is easily recognized by games and I don’t have to mess with mouse buttons 1/2 or go into some stupid left hand mode. I wish the buttons were a little more forward to fit my thumb reach easier but it’s so minor.I’d get another one for my other gaming computer but I’m getting a Naga Left hand edition for my more complex games.

Pretty great mouse!
An incredible feeling top & side to the mouse with solid left & right buttons. The mouse wheel feel crisp and doesn’t slip. The only problem….this mouse is too big for claw & fingertip users and is more for palm users : I was looking to replace my Razer Abyssus Essential, and the Razer Viper Mini is a much better fit for me. For palm users, this would be a 9 or 10/10 mouse.

O mouse é ótimo, mas com pouco tempo de uso já percebo uma das laterais descolando. Uma pena.

Razer es sinónimo de calidad, el mouse es sencillamente bello, muy agradable al tacto y su sensibilidad es fenomenal. La pc lo detecto la momento y enseguida ofrecio bajar lo necesario para su optimo uso en todo sentido.Es muy ligero, su peso es casi imperceptible, su manejo es notablemente mejor que cualquier otro raton que eh tenido.Como todo lo razer, viene en su elegante caja con calcomanÃas, su bolso de tela e instructivo.Completamente recomendable este producto.***El unico detalle es que el repartidor no comunicó su llegada,lo avento a la puerta y se fue sin avisar, lo cual es desagradable ya que puede dañarse o en mi caso que tengo perros, ellos pudieron dañarlo. Ãnicamente por que estuve pendiente de la pagina fue que supe que el paquete llegó. Seguramente fue un repartidor externo y eso habla muy mal de Amazon… En fin.

The mouse cable seems robust to withstand the wear-and-tear of daily use. The RGB feature is a nice touch.
