Pulsar Gaming GearseS ARM SLEEVE A high-strength band for enhanced focus, Reduce fatigue (Palm Short XL Black)

I bought one alongside my glass mousepad and after using it for a session or two I just stopped using it and realized it did literally nothing. Unless you are sweating up a storm in a hot room you won't have much trouble with friction on a glass pad, and worst case scenario you can do something nutty like wearing a long sleeve shirt. This thing is way too uncomfortable to reasonably use all the time when you are playing.
