this is my favorite trackball. https://amzn.to/2DfYuUh ball is in the middle. i can always swap to left hand if right hand is tired or vice versa. Logitech does make wireless trackballs but only for the thumb. for whatever reason, my thumb would get fatigue easily.so is there any way to convert to wireless? i see there are kits to make video game controllers wireless. i wonder if there are such kits for trackball or mouse.thanks! via /r/DIY http://bit.ly/2GsIBgb
