First thing that goes on my mouse is always the feet falling off. I always though you needed to just replace the feet or buy a new mouse. I'm not one that needs any fancy mouse. As long as there are about 4 buttons, I'm fine.
When I was playing WoW, I tried to use a wireless mouse, but the fact that I needed to hold down a button almost indefinitely wasted the battery too fast, so I stick to wired. I don't play games like that anymore, but I don't feel hindered by the wire. Lag was never an issue.
What is the intended purpose for that tape? The reviewers seem to be taping over the mouse feet. The description says PTFE on PTFE contact, so I'm assuming you are to make a surface of tape for your mouse to lay?
Either way, I think I'm going to order some of those discs by the same company for my mouse. Maybe the tape for general use. I'm sure that will come in handy for something, when I think of it. I saw one review said he used it on his drawer rails.
