I have had mine installed for about a month and a half and I haven't had any issues with it, it's still firmly stuck to the door, I didn't use the tacks that were included either, The one in my bedroom doesn't have any clearance issues, but the people that poured my garage slab made it very uneven and the one that's installed out there rubs the floor a lot and it hasn't come off the door yet either. I do want to add that I thought these were going to be a hard plastic, they are not they are rubber, which might seem weird at first but I assure you they work fine. 100% worth the money.
