Essentially, the DeathAdder V2 X Hyperspeed is a budget version of the DeathAdder V2 Pro. Running either on an AA or AAA-battery, the V2 X Hyperspeed has up to 235 hours of battery life in 2.4 GHz mode and up to 615 hours using Bluetooth. PixArt's PAW3319 sensor, mechanical switches for the main buttons rated for 60 million clicks, and pure PTFE feet round things off.
