This has worked surprisingly well at keeping a constantly clogged drain just a little less clogged by longer hairs that come out when showering. The only reason I didn't give it 4 stars is that it pops out from time to time when we try to pop it with our foot. The hair still usually stays in the stopper but also sometimes gets tangled up inside and needs to be pulled out / cut with scissors to get it fully out. But it works smoothly.
