I got one today-it was on the shelf at our local little store for $10.
It works pretty well, it's a reusable lint roller for me. The plastic frame is reasonable sturdy and shouldn't break easy and it came with a little upholstery type brush that works well too. It doesn't rinse cat/dog hair off immediately like they show on the commercial but easily enough, you can run it under water and not have to touch the little sticky roller. The sticky roller has good squish to it so it was nice for rolling the cat hair off my husband's black ball cap, it could work around the seams and button.
I've been pondering that thing for a while and I'm happy to report it's worth $10 to me.
