Review (4/5): Sink drain suction cup by walter drake
It does trap hairs. Loads of hair was in my hair trap and have mercy I never imagine so much hair was going down our drains. No wonder I had clog troubles. I think this trapper will help. The only thing is that the suction cups on the outer edges don't really work. But overall I don't think the suction cups are really needed for it to work.
