I've had mine for a couple of years and I use it on all my sweaters. It works beautifully, gets off all the lint and doesn't damage the fabric beneath, not even tissue thin, single ply cashmere. I can't say why the other reviewer thinks it looks cheap, or what that has to do with the way it works, but I can say that it's saved me a fortune in dry cleaning, which was the only way I could get the nasty looking piled lint off my sweaters before I found this gadget.
