Does anyone here own one of those couch mice, like the Logitech M515 Couch Mouse, or one of those "media center friendly" Microsoft mice? Apparently they have special pads on the bottom that prevent them from sliding off a fabric armrest, while at the same time being smooth enough to feel no different to using a normal mouse on a normal surface. Well I use my computer from a couch, and my mouse slides off the arm rest about 5 times a day. I already broke my last mouse because of that. Without having to buy another one, I was hoping I could DIY something similar, but it would be nice to know how they did it. I tried velcro pads, but that was too grippy. Any ideas?
