Mixed review
I had two clogged sinks, kitchen and laundry room, and had zero luck with drano and such products. Even had a plumber look at the kitchen sink and he said it was just a slow drain. So i bought this after seeing the demo on HSN. (BTW much cheaper on Amazon) Well my kitchen sink now drains like a charm! But this did nothing for the laundry room sink.
