I highly recommend this comb. It worked wonderfully on a bunch of my sweaters (wool, cashmere, etc.). There was no damage to any of the sweaters, and there are very few new fuzz balls. It was easier to use than a scissor or razor and I didn't have to worry about cutting the sweater by accident. Great product!

Works surprisingly well on wool sweaters, and it is easy to use!

This thing ruined a couple of my sweaters! It does remove the pills remporarily but, after using it, the pilling actually becomes worse. I think it tears the fibers and makes them more prone to pilling.
