"I tried this about 6 weeks ago for a slow drain in the bathroom. Had already checked for the obvious clogs but found none. This product is not ""immediate"", but seems to work and I was pleased not to have to resort to the chemicals of the past! Every couple of weeks I put another 2 oz. down the drain to maintain and have had no problems with the drain since."
