RazerViper Ultimate Lightweight Wireless Gaming Mouse & RGB Charging Dock: Hyperspeed Wireless Technology - 20K DPI Optical Sensor - 74g Lightweight - 70 Hr Battery - Mercury White

I wanted to try different mice after using a Logitech G502 lightspeed for a long time. While my G502 lightspeed is by no means a terrible mouse, I wanted something that weighed less and I wanted to try out different mice shapes. After hearing many praises for the Viper Ultimate, I decided to try it out myself to see if the hype was worth it or if it was all marketing nonsense.First off this is an ambidextrous mouse. I am a right handed user and I mainly play with palm/claw grip sometimes transitioning to full palm and full claw grip. The rubber texturing on the sides and its shape makes it super comfortable to use and I have medium sized hands. On top of that, it is really lightweight.The charging dock is an absolute genius idea I wish other big companies would start adopting. You simply plug the dock into your PC, then plug the receiver on the spare usb port on the dock, and when you need to charge your mouse just put it on the dock. If you need to charge it in a pinch, take the usb cable out of the dock and plug it directly into the mouse.Next let's talk about build quality. And boy did Razer deliver. No signs of creaks, has a really solid feel, materials don't feel cheap, and the left/right clicks have really nice texturing on them.Left and right clicks may feel a little off at first if you are coming from mice that have extremely tactile and distinct clicks. That's because they are using optical switches and you may or may not like how they feel but I got used to them pretty quickly. The side buttons however have a really nice tactile feel and despite being an ambidextrous mouse, as a right handed user I never accidently bumped into the side buttons on the right hand side of the mouse. Razer really nailed the side button positioning such that they can't be accidently activated (at least in my opinion).Wireless performance is on par with my G502 lightspeed. No noticeable delays, weird connectivity issues, or any funny business.Battery life is also really good. I usually disable RGB and that really helps with battery life. Sadly I've only had my mouse for a few days so I can't fully test battery life claims.TLDR: An awesome mouse that won't disappoint. I recommend getting the dock combo to get the full experience. I mean, might as well if you're going to drop big money on a wireless mice anyways. I see no reason not to.

Absolutely love this mouse. Lightweight and very responsive, I have no complaints about input delay which was a concern of mine for a wireless mouse. I have put over 1400 hours on it by now playing competitive FPS games and a year later it has held up extremely well. Clicks still feel like they did day one, battery life is still probably 20+ hours of gaming, lights show minimal or no signs of degrading. The razer software for controlling lights and button mapping gives you complete customization. I'm nice to my equipment and this mouse gives me confidence it will perform for a long time.

The best mouse, work like the first day now in 2025 nice movement, nice buttons, perfect size for me, and everything good, I like it more than the v3 actually the grips are top

I have owned Razer mice in the past and always liked the hardware but not so much on the software.I tried an Asus Pugio and was sadly disappointed so I was a little nervous with another chance on a wireless gaming mouse. This time around I knew I wanted a charging dock to make it more convenient to keep it charged.Likes: It advertises as a very lightweight mouse, I thought, 'how light can it be?' - it is very light! I almost wasn't sure I could get used to how light it was as I was overshooting and used to having a little 'heft' to move around. I got used to it quickly, the weight is very nice. The shape fits my hand nicely. Plugging it in right out of the box and before any software was installed it tracked very nicely and moved smoothly. Having the dock also be able to house the dongle is a well thought out touch - however I use it on a laptop and keep it in the machine so I can just grab the laptop and mouse and go without transferring it.Dislikes: I still gave it a 5 star but there are a couple little things I wish it had - a battery percentage for the system tray would be nice, or at least let you set the mouse logo color to show a percentage. The side buttons were a little too flush for me. I like them to have a slightly move raised feel so I get a more positive position feeling and don't feel as though I have to be exactly on the center to depress it, but they still worked well... just a personal preference. Lastly, the dock felt a little more designed to show off your mouse more than for ease of use. I find I have to fiddle with it a little to set it on right and make sure the pins contact. Button press - maybe it's just me but it felt like the pressure/travel was a little high. I really only noticed when trying to click very rapidly and it seemed like I had to lift off more than other mice.Synapse software has come a long way and has been working well. It has improved a lot since I have last used it and feel much more confident using it.Bottom line - I was pleasantly surprised and would buy another.
