Incredible!
My experience with this product has been fantastic. I have three daughters and the upstairs shower is always running slow. We buy a drain opener every few weeks to keep it going and no one likes the idea of using a toxic chemical. The directions say to use it for 4 nights and we did see the flow increasing day by day. I would give this a 9 out of 10.  Also, the little bottles are very easy to deal with.<br /><br />The shipping was fast and simple, it was a well-sealed package on arrival and the instructions were very clear.
