RazerDeathAdder 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

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.

This review is for the Deathadder V2 Pro Wireless.The Value: 7/10This mouse is more on the expensive side, but wow did it come in quick. One day shipping, impressive.The Shape: 10/10I loved the design of the first Deathadder, and it still reigns supreme. I have huge hands (easily can palm a professional basketball) and I’ve struggled with “esports mice,” notably the Glorious Model O Wireless. Button placement is great and it’s perfect for right-handed users.The Buttons/Clicks: 9/10The buttons and clicks feel a bit hollower compared to the Deathadder 2013. There’s just a slight more space needed to register a click. This is not a big issue and I’ve adapted fine. Response times are really quick with the new technology.The Quality: 10/10The mouse is really well-built. The rubberized sides feel good. It’s pretty much the Viper Ultimate specs with a different shell. It’s lighter than the Deathadder 2013 by 20 or so grams, so overall a great mouse.The Software: 6/10Here’s where everybody dumps their complaints. I know, the software requiring a login is dumb and invasive. It’s part of a higher-level product offering ploy. The fact that upon first plugging in the mouse, the computer pops up with an install for synapse and slows the computer down. I get it. My advice: setup an account, make your changes to RGB (which mine is off anyway), DPI, polling rate, etc., program multiple profiles using the onboard memory (in this case I have two DPI’s), then request to delete all of your user data through synapse. Delete account, uninstall synapse, then continue to live your life. You’ll be ok. If your worries about a gaming peripherals company “stealing and selling your data,” you’d be surprised of how much of your information you actually give on a daily basis just walking around in public with your Bluetooth on. Logitech has the same issue, so it’s rather hard to avoid.Overall: 9/10Tl;dr: Great ergo wireless mouse, bad software with easy workaround. Great for people who don’t like the ambidextrous esports gaming mouse shape.Highly recommended.

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!

Why did you pick this product vs others?:Great mouse. Use it plugged in or go wireless. Wish it came with charging dock, but I just plug it in every few days for a bit. Also, my son was a bit rough with it. He rages sometimes and I think that's why the plastic kinda "clicks" on the sides when I grab it. Kinda hard to explain. Don't be heavy handed or let your angry gamer son play with it, and you'll likely be fine. Did buy it open box. Could've been that's why, but I didn't notice it till after my boy was banging the damn thing on the desk 😆
