Bathtub took 2 hrs to drain, caused most likely by trapped hair. I dragged out what I could reach with needle nose pliers, then with that flexible plastic strip with hooks. But most of the clog was too far down to snag. Nothing I tried worked – neither a plunger or baking soda and vinegar or compressed air, and I would have had to dissemble the drain to get a snake down it. It worked like a charm and cleared the clog in less than half an hour. This is an excellent product and did not damage the pipes or the bathtub. Try it before calling a plumber.
