I have very long hair and it would clog up my drain every 4 months or so and we'd have to snake the drain, which is gross, and get the hair out. This drops right in the drain and catches a lot of hair. I've only had it for a couple of weeks now and right before I'm taking a shower I clean it out and there's plenty of caught hair, so it's doing it's job!
