After trying a couple of different chemical drain openers and still struggling with a very slow draining bath tub, I found this and decided to try it. Instructions for use are super simple. Worked like a charm!

It is a good product. Sometimes it works miracles on clogged sinks. Everything seems so expensive with some places ready to gouge us. I would like to see everything be a little less expensive, because it adds up over time.

Best drain clog remover I've ever seen!
I had a very clogged bathroom sink. I plunged, snaked and Drano'd. Nothing made it budge. I was not expecting this to work either. However, in less than a nano second, it was clear. It was very easy to use. Place the cap over drain, cover the overflow with a wet cloth and push. I want another clog just to do this again! The can states approximately 11 uses so it is well worth the price.
