I have been a fan of command hangers since they came out! I've used them all the time and they work perfectly and last for a lifetime! It wasn't until I moved that for some reason they aren't working. I used the same hangers I had in my previous house, just new strips, put on the same bags/items that they were meant to hang from the previous house AND bought 2 more jumbo ones and used them as well but for some reason they aren't sticking. At first I thought it was because I didn't let the adhesive set in before I put on my bags/items. So I tried it again and let the adhesive set in for a day or two. It lasted up on the wall with my items longer for at least a few more days but it still fell down. I know they work because I still have 3 hanging on my wall but I don't know why the other 2 aren't. It kinda makes me question will these last 3 stay up that long? It's really disappointing and frustrating because I LOVE using this product but it won't stick for some odd reason...
