Did not clear clog in sink after several tries and letting sit for several hours. The clog was a few feet after the p-trap and is a recurring issue - it happens where the air condition drains into the sink line, which maybe is not the type of material that this product breaks down.

Took half a bottle but clogged hair gone

Did not clear sink clog, had to purchase a better solution.

Good product, great value, will buy again. Highly recommend

Keep on hand for clearing clogged drains.

It works.

Works as advertised

I haven't had any luck with this product. I have used both bottles in my tub drain and it still doesn't drain well.

Had a hair clog in my bathroom sink. Worked as advertised on the first application. MUCH cheaper from Sam's than big chain hardware store.

My house has the old cast iron drain pipes that clog easily. I have found that Drano Max Ultra Gel works best on clearing clogs in these type pipes.
