I liked it when I first started using it. I saw great reviews so I decided to give it a try. It worked fine for a few days (7 hours total usage) then the sandpaper stopped sticking to the pad. I even swapped out the sandpaper for a new one, thinking I'd already used the sandpaper, but nothing. The sandpaper just falls off. I really want my money back so I can buy a new one. I don't want a replacement because after that I don't trust the brand anymore. I'm waiting for an answer and I hope they honor their 2 year guarantee.
