I love these stair treads.  I had bought some previously from another company and wore out fast!  These are quality stair treads and I can tell they will last some time.  I've had them a year so far and barely any wear on them.  I took double sided tape to hold them in place on the wooden stairs. (not recommending this)  I am not moving the stair treads anytime soon, but when I do I will take care removing them from the double sided tape.
