My daughter loves to take baths, but our tub currently our drain is broken so we can plug it up. Well this is a perfect, easy, cheap way to solve the problem. It comes with 3 different color stoppers. All I had to do was place it in the drain, that's it. No installation needed. To keep water in the tub all I do is push down on it and to get it back up to drain I push on the middle part of it and it pops up. I was worried that it wouldn't drain good because it is not flush with the tub, but it drained with no problems, but does leave a bit of water so all I do remove the stopper till the water is all gone, not a big deal. The design is good. Not sure if it works for catching hair, I haven't seen any hair but we don't always shed hair. Over all it works as it should.
