Double Sided Foam Pads, 66 Pcs Double Adhesive Foam Pads Strong Mounting Tape, Square and Round, Black and White

Wrote another review on a different cut of these. Work very very well and am thrilled to have them!

I was going to return these but felt I had used too many trying to get them to work that it wouldn't be right. I can't say for sure but they don't act like 3M 9448A two sided tabs. I have used different kinds and others hold almost anything reasonable. These for some reason won't hold a 10 port USB hub to any surface for over a day or two. After that it just falls. Cleaned the surfaces and I have tried it on multiple. Either this was a bad batch or they are counterfeit.. I am sending to 3M for them to check,

The black round dots worked the best!! I’m super happy with it. The square white ones, not as good though.

Works on a concrete wall I use it to put up a bulletin board

I use to put photos frames and everything went down in 2 hours
