LZYDD USB Charging Cable for Razer DeathAdder v2 Pro Wireless Gaming Mouse & Basilisk & Razer Viper Ultimate Hyperspeed Lightest Wireless Gaming Mouse(Micro Port,Not Work for Viper v2 Pro)

I decided to update the firmware for my Razer DeathAdder V2 Pro's USB dongle, and the next step was to update the firmware for the mouse itself. For this step, it asks for you to plug in the mouse with the cord that it came with. I must've tossed the cable along with the box for some careless reason because I couldn't find the cable anywhere. Because of this, I essentially bricked my mouse because it couldn't connect to the dongle anymore. Thankfully, ordering this very high quality cable helped me to update the mouse's firmware and get it connected once again wirelessly. Highly recommend this cord if you need a replacement.

worked for my viper ultimate

I originally bought this as a spare cable for charging my mouse, but ended up swapping out the crappy cable that comes with the Razer Nari Ults w/ this and so far they've held up great.If you're looking for a durable and lightweight cable to charge your headset while it's in use, this is it.

Will update after another year if I remember

I bought these after being impressed by the durability on my ultimate viper charger which is identical to this. The best micro USB cord by far, never come out on their own. I've tried 3 other similarly priced brands, and they don't even come close 10/10

This def works like it’s supposed to. Works great.

Amazing :) real happy with it.

Good
