RazerViper Ambidextrous Wired Esports Gaming Mouse: Fastest Mouse Switch in Gaming, 16,000 DPI Optical Sensor, Chroma RGB Lighting, 1000 Hz, Optical Mouse Switches, Onboard DPI Storage - Black

From 10 hours straight of intense usage, this is the new gaming golden standard.The good:First, the coat feels great, if you have sweaty hands you can use the already included grip tape and place it on your mouse, I have it on the left and right sides, as well as the left mouse button. But the feel of the mouse without them is still good. Some people say that the black coating feels better while others say the white coating feels better, I only have the white so I cannot attest to that but it is something to keep in mind. The scroll wheel feels comfortable, the clicks feel good, and the side buttons are responsive but squishy in a way, which I find nice. Jumping from 1k to 8k hz polling rate is noticeable for the better. The mouse's weight is extremely light (coming from a previous 112g mouse) but the skates on the bottom of the mouse don't feel like they will make the mouse slide out of my hand or not move at all. My favorite part about this mount is the extensive performance settings and battery-saving settings. First, you have an option in Synapse to change the polling rate while in fullscreen games, which is useful for extending battery life, eg. 1k on desktop, 8k in competitive games of your choosing. It also has a defaulted-off setting called dynamic sensitivity which is mouse acceleration, which you can customize and there are already presets, which is nice for those who don't want to look for third-party programs and go through rigorous testing. Something that probably won't be talked about but is most likely my largest preferred feature is under advanced and is called rotation. This allows those who play with their hands or arms at certain angles who have to adjust their cursor horizontally, I have it 2 degrees to the right and it has most definitely eased the stress of having to adjust for wanting to go straight but going down or up. In terms of the mouse shape, it falls in line with your wrist smoothly, it is good for small/medium hands, I'm not sure how people with larger hands would feel, but I would recommend the Deathadder for that as it is suited for larger right hands. There are power saving such as idle time, so if the mouse is idle from 1-15 min it will toggle off and save battery and go back on once you move it. It has a low-power mode that will switch on and limit the mouse at a battery percentage of your choosing. The white braided cable is good, the 8k receiver has rubber grips so it will stay wherever you put it. USB C to USB A connector and charger, so it is convenient for a PC setup and to charge.The bad:While it is a performance mouse, I would have hoped there was a little more RGB in it. The only lights that exist for this mouse are the small lights on the 8k receiver and the light at the top of the mouse near the scroll wheel. The mouse light is only on when you change sensitivity, the 8k receiver light is only on according to the setting you choose: Connection status (white light), Battery status (Green 100%, Yellow 66%, Orange 33%, and Red 0%), and Battery Warning Only (Off at all times and only blinks red when mouse needs to be charged. Some people have seen issues with the tracking distance, personally, I haven't run into that in 10 straight hours of using this mouse once, and I have it set to medium. But it is what others have said.In summary, this is an expensive mouse for sure, but it is justified. 8k polling rate, super lightweight at 54g, including comfortable (and possibly sweat resistant?) grip tape, good skates, highly customizable performance, and battery settings, good mouse feel and shape, as well as a highly respected and recognized brand. I can see a large majority of Esports mouse and keyboard players choose this as their mouse.

This was very good specially the battery life.I had the Viper ultimate and it was lighter than that.

its light-weight and very responsive and quite durable, i would suggest this mouse to anyone who would try to improve his gameplay or overall performance, the mouse feels super smooth and the light weight makes it really easy to control

loose clicks when it came, now they became more loose almost locks when clicking

Worked perfectly fine for a week, then the USB wireless dongle randomly stopped pairing with the mouse, and, and ryzar synapse wasn't detecting it when connected either. the only way to get the mouse to work then was by connecting it using the cable. tries on different other pc's, nada...had to order a replacement the same day. waiting for the replacement to come I hope it isn't a common issue with the usb dongle.

I recently bought this mouse to play fps games and im absolutely loving it. i got the mouse in the used but good condition and nothing is wrong with it

This mouse is so good I had the first Razer viper ultimate V1 and it had some problems this V2 is way better it’s lighter then the V1 it charges so fast and lasts way longer highly recommend

Yeah you are not gonna use 8k polling for most games. 4k polling is nice but not too different than 1k. You have to be playing a really fast paced game at very high frame rates to really notice the difference.Otherwise the mouse is fantastic. The stock skates are the best I've ever used but my artisan zero did shave them down quite easily. The sensor is fantastic. The accuracy and tracking feel spot on. It isn't a safe shape but it works for my hand/grip style.I probably won't go back to my superlight any time soon.
