I used these to keep the metal hasps on a sliding shed door from hitting the shed trim when opening and closing the door. These are way over kill. I should have bought magnets 1/2 this size or less. I based the purchase on the size of the hasps which are about 1-1/2" wide. Now I think a 1/2" magnet would've done the job nicely. Although they weren't the best for my use it wasn't the fault of the magnet. So 5 stars for the product and 3 stars for me. LOL.
