well yes, you can in fact glue them back in with some special glue and much effort, then clean up with a scalpel, then ... but it's not worth the time.
Yeah, I could use UHU Por and it would come out good, but what happened was that one of the Teflon corners turned downwards while I was pulling it off, and that kept catching on the mat forever after.
Yep, had that before. So i decided to cut away the Teflon around the 5 screw holes using a fresh (=really sharp) carpet knife. Nothing bent, no protruding corners, same gliding performance with just a different look from the now exposed holes at the underside...
