The adhesive really only sticks once, so it doesn't reposition easily. But, the glue works just fine and lasts as long as any other. If you didn't position it right the first time and if you have the room, you could super glue to the magic carpet to another piece of tape, then put the combo where you want the carpet. I've worn the carpet out well before I had any adhesive issues.
