Viper 8Khz - Esports Gaming Mouse - 8000Hz Hyperpolling Technology, 2Nd-Gen Razer Optical Mouse Switch, 71G Lightweight Design, Advanced On-Board Memory - Classic Black

After using a cheap gaming mouse for almost a year which i thought I was satisfied with, but when I switched for this Razer mouse (this is the 2nd product I buy from them) I IMMEDIATELY !!! felt the difference. I swear mouse flicks, tracking, general use and the glide over the mouse pad felt Significantly different it LITERARY feels like part of your hand

The mouse is great very responsive, and has long cables. Response time and holding feel is good, it is light made especially for gaming. What I did not like is the quality of plastic, does not give it a premium feel, the switches seems to be ok and responsive

Nice

My unit came and had disconnecting issues ever since ive gotten it, not only could I not issue a refund but until today(8th of june), the mouse buttons were working just fine, mine just so happend to stop clicking and wont functoin Size and shape are good and the ptfe feet for my G sr mousemat

Tried it on two devices. One has it almost consistent every time, I need to remove and plug the USB back again for it to work. The other device I tried it on, it happens occasionally. Very disappointing.

Not good for FPS games. It has a massive clicking problem. My friends had warned me, but i still went with it. It miss-clicks when you click back to back in shooting games.

best mouse money can buy u , I bought this for my son Cr7 JR nd he loved it , u get almost no delay (,<0.250ms). extremely durable I threw it from the 15th floor nd it still worked flawlessly. The mouse can be used without a mouse pad (if ur broke). Overall the best mouse ever , I am a professional gamer with 10k+ earnings in various games like CSGO, Valorant and fortnite .

Just a small PSA I had to order the product twice as the first one from TJDesigns was the wrong item (Normal Razer Viper), however their customer service was excellent and I was given a refund following the return of the item. Now, to the mouse. The mouse is excellent. The 8KHz might seem overkill and you don't really feel it but it could be future-proof I guess. The focus+ sensor is top-notch and tracks excellently. I had a few issues regarding the lift off distance on my worn out mousepad but after using the calibration feature along with the LOD adjustment in the Synapse 3 software I no longer face too many issues. The shape is not bad. Took a few days to adjust to it since I was used to the Model O - and primarily use claw/fingertip hybrid grip with 17x9.5 cm hands. Still on the bigger side personally, but once adjusted feels great. The sides are very grippy and helps with sweaty hands. Buttons feel excellent. The main buttons had no wobble on my product and feel crisp and mechanical. Side buttons had no wobble as well and isn't hard to reach. I do press the RH side buttons occasionally but isn't too much of a bother. These can also be disabled completely in the software if you face this issue with your grip. The mouse chord feels a little stiff and I would recommend getting a mouse bungee as you do feel the drag of the cable. PTFE feet glide very smooth out of the box but I would need to update it after a few months of use to notice the feel after wear. Overall, definitely one of the best mice I've used, feels great in the hands and probably going to be my main one. TLDR: Excellent mouse with top notch sensor and crisp buttons. Great build quality. Cons: Might take a while to get used to the shape (slightly big for smaller hands), stiff cable, might need calibration or LOD adjustment before first use.
