The installation of the product is simple enough - clean area you want to place the hook; let it dry; then pull off the adhesive covering and stick. Also, give the square a little scratch to ensure a good hold. Allow for the full time for the hook to set before trying to place any coats on the hook. I’m not sure it can hold 44 pounds b/c I tried to hang my purse on it and it fell. And it’s between 10/15 lbs. Overall, it looks nice on the wall, it is functional and it was a good price for the money.
