It really Works
From time to time, our tub starts to drain slowly.  A few years back we ran a new line al the way out to the sewer line and added a clean out but for some reason it still tends to run slow.  We happened to be watching tv and this product came on.  It was being demonstrated in such a fashion as to show how blockages would be removed.  So we purchased this and it works fantastic.  We have been using it for quite a while now and will continue to use it.
