“Lowering the actuation depth improved my reaction time in competitive games. Analog mode in racing titles feels surprisingly natural. The mouse glide is smooth.”
“I thought the macro didn't have infinite repetitions, but there are no helpful images anywhere on the internet. I still haven't found the answer.”
