I received this product free from 3M. They hold very well, I used 1 on a medium all glass picture frame. As long as you follow the instructions properly, they work. The 1st one I tried, I did not clean the wall with alcohol, therefore the strip came off. However on the 2nd try, it worked. The picture frame is a bit heavy and I only needed 1 strip.
We decided to try Command Products to hang most of our pictures. They are really terrific. I didn't try them on my larger paintings, but all the rest of them stayed on. We just had some painting done and they came off so easy. I recommend them to everyone.
