I used this roller for quite a while before I switched to the Therm O Web roller. I do like the product, but I DON'T like what a pain it is to refill. I liked the adhesive itself. It was permanent and did stay in place. When the roller was working well, it was awesome. BUT when it comes time to refill it, you have to roll it just right to fit it in the dispenser and cut the little tail. I am a very common sense person, but this part of the product really irritated me. It seemed every time I thought I got the refill in, it would get hung up on itself and I would have to start over (seemed like a lot of waste to me!). Not to mention all the little adhesive "goobers" that pile up.
