Rated 1.8 out of 5 by 56 reviewers.
Rated 2 out of 5 by Good For Minor Clogs This worked "ok" on my bathroom sink for hair clog (but could have just as easily did a plastic snake). I did not use the entire bottle. It did not however work my shower drain. The water still collects as it did before. I used it per the directions....and then nothing. A little disappointed. September 1, 2014
Rated 1 out of 5 by This doesn't work This stuff was as useful as just simply pouring more water down my drain. What a waste. July 21, 2014
Rated 1 out of 5 by Didn't work I tried this on my slow bathroom drain, and it didn't do anything. Drain is just as slow as before. July 6, 2014
Rated 1 out of 5 by didn't work I bought it, in part, because it says "GUARANTEED" on the bottle. I poured the whole pottle down the sink in our half bath our slow drain did drain, but I went back to try the drain later and now it's completely clogged. September 4, 2013
Rated 1 out of 5 by DOES NOT WORK DITTO from the previous commenter. This is like throwing a 5'ver down the drain. Blocked solid now - Trying something else...Will be getting my money back October 20, 2013
