I don't typically write reviews here on Amazon, let alone negative ones. But I felt this product warranted one because it was simply useless for me. I purchased these as a refill for the standard white 3M small strips that come with the small wire hooks. I couldn't find the normal ones so I ordered these. I figured why not, they're made by 3M?
Within hours after properly applying and hanging four items on my walls using these refill strips, I had three of the items fall. I had hung these four items in my previous living space with no problems using the standard white 3M strips. One of the four items had its frame irreparably damaged; thankfully the art was unscathed.
I promptly found and ordered (at higher cost) the standard white strips and have since re-hung the four items previously mentioned. None of them have fallen this time. They are mounted in the same places that I tried these clear strips.
Don't buy these. Buy the standard white strips.
