Razer DeathAdder V2 Pro Wireless Gaming Mouse: 20K DPI Optical Sensor - 2nd Gen Faster Optical Switch - Chroma RGB Lighting - Up to 120hrs Battery Life - 8 Programmable Buttons - Classic Black

Overall - a fantastic mouse. Everything is still working 2.5 years later, and working well at that. No erroneous scrolling while the wheel moves, the accuracy is still very much there, and the battery life is certainly long enough for multiple full days of gaming if needed - but, can also be plugged in while using. I'm not much of a customization guy - but it's most certainly there if you need it with the Synapse program. Can't recommend enough!

I've been using DeathAdder mice for 12 years and this is my favorite one yet. PROS: - Ergonomics for 8+ hour workdays or 8+ hour gaming sessions. Your eyes will hurt before your hand. - Physical buttons to easily adjust sensitivity / DPI - HyperSpeed is VERY snappy. No impact to FPS games coming from older corded versions. - Multiple wireless options makes this a great travel mouse. Bluetooth + HyperSpeed = Versatility. - Sweat resistant. I notice I'm spending less time cleaning this one than prior versions. CONS: - Battery life leaves something to be desired. I'm getting maybe 40 hours (3 days) on a charge. Why not v3 Pro Wireless? COST. Is the v3 double the mouse? Am I going to double my performance with a lighter mouse? Will it make me 1.5-2x happier? Probably not. I'm sure the v3 is an excellent mouse, but at $150, it's currently priced for enthusiasts. I think I'd rather own two of the v2! Overall, after 4 months of use, I'm extremely happy with the v2 Pro Wireless. Yes, the battery life could be better, but we're spoiled compared to even just a decade ago when a wireless mouse wasn't even a real option for gamers. It's a good decade for the gaming generation who's also working from home.

I bought this mouse as an upgrade when my original Razer Deathadder started malfunctioning, and It was definitely worth the price. The mouse is extremely responsive for a wireless mouse, being just as fast as a wired one. It has a Bluetooth mode, and a separate mode to connect to the USB receptor, meaning it can theoretically still be used even if the receptor is lost. It has a small rainbow LED light inside of it, which causes the logo to light up and change colors. It's made of a mix of high quality plastic and rubber grips, which gives it an amazing, quality feel in the hand. Additionally, I find that the mouse is extremely responsive, even on a variety of unorthodox surfaces, such as carpet, blanket, and more. Contrary to some reviews, it does come with a charger! The charger is specifically fitted for the mouse, with the end sliding seamlessly into the base. The mouse can be used while charging, not needing to be unplugged while in use. The other side ends in USB, so It can be plugged directly into the computer. The battery life will last you a while. I haven't had it die on me during use, but I usually use it plugged in, only unplugging it when I need to use my laptop somewhere other than my desk. Still, one could leave the mouse charging overnight and use it unwired throughout the day without issue.

Mouse gets 5 stars. Smooth moves, perfect clicks, cool RGB, 3-way connection option all as advertised. I have fairly big paws and it's fits me perfectly. And the Razer app is simple enough to navigate and useful. Amazon resale gets 2 stars. Product arrived in plain cardboard box. No paperwork whatsoever. Just mouse, cord, and extender. Plugged it in to my laptop and nothing. Cord had bad kink and it appeared to be the problem. Connected mouse to computer by Bluetooth and it worked amazing. But battery meter on app showed at 42% and dropping. No cord connection no charge. I love the mouse so rather than send it back I ordered a $10 aftermarket cable that fit Razer's proprietary micro USB port. Bada Bing the mouse connected to my computer by the cord. Now it charges and works in "Wired" mode. The moral to the story is Buyer Beware on the "Like New" description for used items. To their credit the mouse itself was like new. But new, used or otherwise the Razer Deathadders are awesome!

So to clarify, I have been using the Deathadder in one form or another since approximately 2012. Since that time, I have gone through approximately 5 or 6 mice, that have all broken for one reason or another. Quality aside, this is just my comfort mouse, it's what my hand is used to having a hold on, and the DeathAdder V2 Pro Wireless is spectacular. It feels excellent, it has wireless and wired capability, it has a solid weight, the buttons on the top of the mouse near the scroll wheel are programmable, and most of all the grips on the side feel divine. I absolutely love this mouse. I did take 1 star off of my review for the aforementioned quality. I have always had some problem with my Razer mice, and it always seems to surface in a relatively short time after purchasing the product. With this mouse, when you are using it in its wireless mode, it will start doing this thing where the mouse gets stuck in a boot loop and it will sit there and reconnect over and over and over again. The problem with this is that if you are in the middle of doing something or playing a game that you cannot pause, AND you don't know why its happening or what is going on, it can be an extreme hurdle to get over. In fact, I'd wager a lot of people don't even try to troubleshoot it and would have just returned the mouse. That being said, there is a fix for the issue, and there is also a workaround, which in my case was just using the mouse in wired mode. But there is an actual fix for the boot looping problem, I just haven't bothered with it because I'm lazy. In the context of buying specialty products like this, it is really hard to beat what your body is used to using, especially if you have muscle memory on your side. It is not uncommon to forego quality in favor of getting something that we are used to using. In this case, I did not expect there to be lack of any quality, but as with all things Razer that I have ever owned, there always seems to be a hiccup at one point or another.

Excellent product

The battery no way can last for 70 hours. It used 10% of battery for 3 hours of gaming I tested so far. Max 30 hours.

I have owned this mouse for about 2 years with mixed feelings. Firstly, I want to say that razer nailed it on the shape and quality. The mouse has held up to thousands of hours of use and abuse. The buttons still click, the mouse the wheel still scrolls, and the feet still glide like the day I first connected it. That being said... the wireless is flawed. To start with... I have no idea what my battery life is at without digging into synapse. Seriously, how hard would it be to have a battery meter on the task bar? I would even take a floating widget. The only other reason I use synapse is to shut off the RGB to stop it from using the precious little battery life the mouse has to begin with. Did I mention the battery life isn't anywhere near the 70hrs claimed? I'm lucky to get half of that. Maybe even less. Charging is slow, and requires a proprietary cable. There is an optional dock that can be purchased for a as much as a wired mouse, I know... I paid it, but it's sort of useless because you soon realize that you can't use your mouse when it's on the dock, and most pc's won't full power the usb unless awake. So you put your mouse on the dock overnight believing it will be fully charged the next day, but surprise... it's still dead. If synapse had a keep alive till the mouse was charged I would be okay with that, but it doesn't To add insult to injury, the wireless sometimes has random gremlins like stutters or ignoring the y axis. Could be tied to low power, I don't know, but this is absolutely infuriating when gaming. Most of the time I run with the cable in. Works great as a wired mouse.

It’s an amazing wireless gaming mouse. Great weight, build quality, shape and very responsive. I personally really like the switches on the mouse but some may disagree.

Mouse is sturdy and well-built - doesn't feel like a cheap blob of plastic, but also is light enough without straining my wrist after 10-12+ hours of work. Buttons aren't overly loud and are satisfying to press. Performance is more than adequate. Battery life is decent. I use this mouse for accounting and design work. It replaced a Logitech G305 and a ROCCAT LEADR, which were both heavier units. The ROCCAT was a better-looking and more sturdy unit, but it was too heavy and big for many continuous hours of use, and also much more costly. Only complaint about this Razer mouse is it's still pricey for a mouse, and the design is quite boring - nonetheless, I didn't buy it to look at.
