My Roccat XTD of 7 years was pretty much unusably worn out, so I purchased a used one, two actually (they are no longer made). The previous user had replaced the feet with PTFE stick-on dots. I have never seen this done before. I like the way that it feels and glides. These a kind of misshapen and uneven, but I may experiment with these. Has anyone else ever done this when the original mouse feet were not available?
Also, he had placed an adhesive grippy strip on the side of the mouse which I am actually loving. It's called "Lizard Skins" and there are lots of varieties, but this one is meant for wrapping lacrosse sticks. I just purchased a roll and I'm gonna use it on some of my other mice that don't have grip- including a Deathadder and my Pure Owl Eye. This is a game changer.
