Promising review: "I've been very impressed! It's tall enough to fit easily over my pop-up drain and (even without suction cups) the weighted top keeps it in place. I have medium-length hair and seem to shed almost as much as my cat, but the drain protector catches it all and the hair is easily removed and tossed away. Best of all, the silicone doesn't hold onto mildew or mold. I have been able to spray and wipe away any grime with very little effort. It looks like this drain protector will last a very long time. This has been a very worthy purchase!"—Suneimi
