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.

I've been using Razer products for a number of years, in particular mice. This is hands down the best Razer mouse I've used so far and possibly the best mouse I've used as well. I haven't been on the bandwagon for lighter and lighter weight mice. Now I might have to jump on that train because the Viper Ultimate is so shockingly light I have a hard time believing that it still works. Previously I had the Razer Taipan and perceptually it's about 2.5 times heavier. The transition over has taken a bit of time to get used to but I do like it. It does feel like you can rapidly change the direction the mouse is moving without much effort and it could lead to better performance playing shooters in particular.Both the Taipan and the Viper Ultimate have rubber grips on the sides of the mouse, and I think It's a really nice feature of both. I've used wireless mice in the past, a Microsoft one that failed me several times in the heat of battle that used AAA batteries. I was really unsure about using a wireless mouse again but I figured it was about time to try one again, possibly the technology has improved over the years and certainly it has. I was tempted by the Razer Orochi v2 but I didn't want to be buying batteries over and over. I think the Viper Ultimate is a bit better for my personal preferences and I really do like it. I was watching some YouTube videos analyzing the latency differences between current wireless mice and wired mice. For the first time I think wireless mice are so competitive with wired mice its there is no major reason to be using a wired mouse outside of cost. The Razer Viper Ultimate is a great example of this. There may be a valid argument that the Viper 8k has superior performance over the Viper Ultimate Wireless but the mice refresh rate is so far above what most monitors can display at 1000Hz pooling rate It doesn't feel like there is a major reason to be concerned about it. Not only that but I've heard the processing required to keep track of the cursor at 8000Hz actually drops your in game frame rate by about 3-4 frames per second (depending on your hardware configuration of course). I don't see the benefit of a 8000Hz pooling rate right now. In the end I think it's a great time to transition to a wireless mouse if your interested in it and are able to afford it.I purchased the version of the Viper Ultimate which included the dock and I'm glad I did. The dock has a magnet on it which makes far easier to rest the mouse on the dock in the correct position for it to charge and you really just don't have to think about dropping the mouse on the dock, the convenience is great. My only complaint about the dock is that it's so light that sometimes I pull up on the mouse and the dock actually lifts off my desk because the magnet is strong enough to carry the weight of the dock for a few seconds before it drops. I guess the engineers of the mouse decided to add a sticky pad on the bottom of the dock to help with this but I think this is a lame solution. A weighted dock design would be far superior in my opinion and hopefully it will be included in a future release. I don't like the thought of a sticky pad on my desk, it might make a gross sticky mess (which thankfully it hasn't) and possibly will become a hard dusty mass in a few years time anyway. That's really my biggest complaint with the mouse/dock combo.A minor issue I have with the mouse itself is the Teflon feet. I wish there was a larger Teflon pad at the back end of the mouse, or maybe two separate feet that are larger that covers that back end area a bit better. In the past I've used mice for years and years on end before replacing them and the back end of the mouse get's the most feet pad wear (at least for me). I feel like the Viper Ultimate may not last as long just because the back end feet are not significant enough and they are positioned far to the sides of the mouse, to the point I'll be lifting the mouse up off the mousepad surface and then setting it down, back down back end first and dragging the plastic of the mouse on the plastic mousepad surface for a few moments before the Teflon feet make contact with the mousepad. This is not ideal in my opinion.Razer synapse, I personally don't mind running software in the background for peripherals as long as it doesn't take up too many system resources and Synapse doesn't. I HATE the way one has to log into an account to make use of some of the features. No mouse should require one to create an account to make full use of a mouse, that is a garbage idea for user convenience. I personally think convenience should be prioritized over most aspects of a products design and this causes me anger every time the synapse software asks me for the password that I usually have forgotten in the weeks that go by where I don't have to enter the password. Even if I tell it to remember my password the Synapse software still asks me for my password from time to time (I think when it does an update). It's difficult for me to put into words how rage inducing this is, mostly because it feels so unnecessary. The software should remember your password no matter what, #1 and #2 you should not need to create an account to make use of mouse software, It's trash on two fronts. Okay, Razer is a business and they feel like they require minor tracking of their customer base so they can make better business decisions and satisfy customers. I don't like it at all but hypothetically I can understand. Message to Razer: Make the Synapse software remember your log in info no matter what. This software design is just as important as your hardware design work. For over half of the use of my Razer Taipan I didn't use Synapse at all because it was such a pain in the rear end to make sure I'm logged in all the time. This may indeed only be an issue with the older version of Synapse, so far I haven't had this issue since purchasing the Viper Ultimate. I really hope Razer has resolved this and I no longer will be plagued with login requests.In the end very few products are perfect and it is hard to fault the Viper Ultimate Wireless with very much. I think it's a product worth buying and I'm glad I purchased it, I hope it will last me a few years and be a valuable part of my gaming hardware arsenal. If you are at all on the fence about purchasing this mouse, I wouldn't hesitate too much, its pretty awesome overall. It is a bit more pricy compared to some wired options but I do prefer wireless over a corded mouse even with a cord bungie (which are really great by the way). Definitely consider the Viper Ultimate Wireless mouse if your in the market for a mouse, It's a great option in my opinion, despite my complaints.

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.

I have actually purchased this mouse a few times for me and as gifts for others.The shape and size feels nice in my hand. While it requires a dongle to connect wirelessly, I have never had an issue losing connection.I like that it can be used wired or wireless, when wired it will also charge while in use, which is so much better than the brand that requires you plug the mouse in at the bottom.I do find that it charges quickly and holds a charge for a long time.
