I would not recommend this product. Does it work? Yes. I first used it in my tub and it did work - got all the nasty hair and gunk out just fine. BUT THEN I used it in my bathroom sink. I stuck it in (just like I did with the tub) and it immediately got stuck. And in the process of trying to pull it out IT BROKE. There was a piece just sticking out of my sink. My boyfriend and I (who have zero plumbing knowledge admittedly) frantically started googling to figure out how to solve the problem. If I had needed to call my landlady she would have been very mad at me and I probably would have had to foot the bill for a plumber. But luckily my boyfriend was able to figure out how to take apart part of the pipe so we could pull it out. It was a HUGE PAIN. This product is CHEAP FOR A REASON. Either call a plumber or buy a heavy duty drain snake that won’t break off.
