Vibration Feet
I read the blurb somewhere about the vibration feet and careful not to peel the adhesive off. Well I got the first three on with no problem, and the fourth one it kinda just came off. I was able to double over some of the adhesive tapes get it to somewhat stick, but it is not real secure.
Not sure how well that is going to hold up?

On my kit build, two of the angled rubber feet came off while I was still building. My fault to some extent: I had dragged the printer over my work bench a few times. The adhesive staid completely on the printer's metal frame; just the clean rubber part came off. But the adhesive was pretty stubborn when I tried to clean it off the metal part!
I cut some double-sided carpet tape to size and stuck that on as a replacement -- but noticed that the rubber was really adhesive-repellent, and could not get a decent bond. Roughening the rubber with fine sandpaper did help though; a couple weeks later and my printer still has its four feet. (I am careful not to push or drag it anymore...)

RE: Vibration Feet
All the feet fell off as of this writing, I am about 45% of the way of building my kit. I wrote Prusa about it. The adhesive that adhered to the frame I can't get it off easy but it came clean off the rubber feet. Funny the LED strip in the heatbed did the same thing but I was able to recover from that as the tape stuck back . I am trying to be careful.
I have some 3M 2x sided tape I will stick them back on when I complete the assembly.
The LED strip was my fault, easy fix, the adhesive tape on the rubber it just does not stick to the feet.
RE: Vibration Feet
Just received the Core ONE kit last week and finished assembly yesterday. Had to move it around during and after assembly and had two feet come off as of today. The other two are holding on, but they are already feeling a little weak. Jumped on to support and have some replacements on the way, but the crux of the issue here, as was pointed out, is that the adhesive just doesn't stick to the rubber. Both feet that came off left the adhesive on the frame perfectly intact. Too low of a surface energy on the rubber for the adhesive that was used. It's a shame, because when attached, they do well to decouple the vibrations from the printer to the table, but they can only do their job well if they remain attached.
