I've heard this same complaint from others on the forum, the Logitech M570 rubber feet stink. I use two of these mice as daily drivers, one stays at home and one is portable for work.
At first the rubber feet were falling off and all I had to do was super glue them back on, good to go. But it seems that now they are falling off in bits and pieces.
I'm interested to find out, has anyone found a solid replacement?
Some ideas:
Self adhesive rubber feet such as these:

What I think would be ideal is some sort of flat rubber material. One that is good enough to fit the entire base and allow cutouts for the battery bay and on/off switch.
Has anyone tried this? It sounds silly, but searching for one foot thin rubber material seems more difficult than previously imagined.
