Review on Renewed Razer DeathAdder v2 Pro Wireless Gaming Mouse - Classic Black with 20K DPI Optical Sensor, 3X Faster Mechanical Optical Switch, Chroma RGB Lighting, and 8 Programmable Buttons by Ashton Dahmer

I bought this mouse first because I had the wired version for years and wanted to upgrade. However, as soon as I took it out of the box, the firmware actually crashed my PC whenever I opened a game and strangely caused problems with my WiFi. I had to do a few troubleshooting steps that didn't work to just use the included 2.4 WiFi. Using wireless also caused my Wi-Fi signal (2.4GHz bands) to be very slow or just drop out completely. Use the supplied USB cable.
