Razer Viper 8K Hz - Ambidextrous E-Sport Gaming Mouse with 8,000 Hz HyperPolling Technology (Optical Focus + Sensor with 20K DPI, Optical Mouse switches, 71g Light) - Black

This is an interesting mouse. Idk what Ibwas really expecting when I ordered it. I really like trying different types of mice and currently own a good deal of the more popular mice. The Logitech G305, 502, steelseries Rival 500, 600. Evga Torx carbon, Razer Basilisk, Deathadder and now the Viper. Corsair M65 elite and an Alienware AW558 that came with a monitor I bought. All have their plus and minus, but until I recieved the Viper I was using the Deathadder.The Viper is a pretty small mouse. I was surprised how thin and short it actually was. I have somewhat small hands so it doesnt bother me. It's ambidextrous, but feels surprisingly comfortable in the hand. It almost feels like it's not made for either hand in a way. It's great how they managed that. The left and right click feel very satisfying, almost like a deathadder, but not quite as light, closer to the deathadder than any other mice I own though. The side buttons are pretty close to flush, but still has that razer satisfying click. I think Razer has the best buttons of any mice I've used and that's no different here. The buttons are small, but it's a small mouse so... the cord is AMAZING for a stock cable and easily the best cable of any mice I've used to date. It almost feels like a shoelace. A quality show place that is somewhat stretchy.I havent had time to use the mouse over a long period of time, well, because it just came out, but I have no problem saying it's well built and should hold up nicely. It's a bit on the expensive side. If you have a little rodent you like using now then I would stick with what you have until you find this on sale or a warehouse deal. Its apsolutely worth picking up, especially if you're already in the market.I personally dnt find how light it is to make a difference, I think that's all marketing garbage and the market has just swung atm to wanting lighter mice. You would have to be one weak wrister fella for 20 grams or so to make a difference. Doubly so for thinking you can move a 60 gram mice faster than an 80 gram mouse, but hey, if you do have wrist issues then you should be looking for anyway to game without pain or the least amount of strain on your wrist possible. I would say it's good for that.Overall, I'm pleased. Its something different and fits good in my palm. Might be a little small for palm grip if you have meat hooks for hands, but I'd say it's great for fingertip or claw grip anyway. Use Amazon's return policy to your advantage!

To be honest, I've had less than favorable experiences with Razer products around 2014-2016 and moved away to other brands like Zowie, Logitech, SteelSeries, HyperX, etc for all my gear. With the recent trend of lightweight mice with holes, I started to wonder what the fuss was about with this mouse (having no holes weighing 69grams).Pros:- Coming from an FK2, it fit me perfectly with my 18cm x 9cm hands (fingertip grip + base of my thumb).- Onboard memory FINALLY. Synapse no longer mandatory for setting it up with your preferred DPI.- Optical switches. Feel a little different (idk hollow?) compared to OMRONS or HUANO switches, but eliminate delays.- Extremely tactile scroll wheel with 24 steps (HUGE upgrade from Zowie wheels) and still smooth and relatively quiet- NO HOLES lightweight design- Turning off the RGB LED gives it a clean look (no logo outline can be seen when its off)-Ambidextrous design but in a way that you will NEVER accidentally click the side buttons on the other side.Cons:- Can't see anything wrong with it after a week of use- So far the only thing that could be wrong with it are people complaining that the mouse feet aren't as smooth like those on the Model O and new mice coming out but its still great for stock feet (it's fine for most people, especially if hyperglides arent a must for you, there could be aftermarket ones later anyways like most cases)GOOD JOB RAZER. definitely a step in the right direction. maybe not step, more like stride, it was a big one.

I wanted to work on improving my aim and so I bought this mouse since it was very lightweight which means less force to start and stop moving it. I can definitely tell the difference, even just using it for work I could tell there was much less strain on my hand/ wrist. Previously I was using the Razer Lancehead due to its good reviews on reliability and I used all 4 side buttons for extra functionality at work. While I still have my Lancehead which has been reliable I wanted something better. I can tell the feel in the hand with the Viper is so much better even though its still ambidextrous. I had just gotten used to more of a claw grip due to the mice I have used in the past but the Viper really works for more hand styles. With my small hands the feel is like an in between a claw and palm grip but I can tell it would be good for either. I can tell the main issue with the lancehead other than weight was how flared out the back was. Another good thing about the Viper is the cable it comes with. Due to the limited space on my desk I'm forced to have my JDS Element 2 above my mouse mat which previously would move your mouse a little if you let go because of the strained against it. The cable the viper comes with allows more leeway before it gives out. Side grips are also a benefit and I have not had any issues with it pealing off or anything. Definitely give this mouse a try.

This is a really good mouse but I have my issues with it. I’ll keep testing it out for another week or so, but I might end up switching back to my DM1 FPS.Pros:It has comfort grooves without an annoying hump at the top of the mouse or honeycomb holes. The clicks feel different but in a good way thanks to optical switches. It has a good sensor. The scroll wheel button is less awkward to press down than other mice I’ve used before and I’ve had no problems with accidentally clicking the side buttons.Cons:Compares very closely to the Glorious Model O, but is more expensive. It’s a tad bit too small for my hand (palm grip). Just enough to make it uncomfortable and worsen aiming. The mouse pads don’t glide very smoothly. I also get very hot, sweaty palms while gaming with it. I don’t have this issue with the DM1 FPS(matte). The cable isn’t shoelace like Model O , more like Final Mouse.
