The video is misleading
Unless you clog is on the same side you see in the video, it does not work. I have a slow drain but the clog is past the trap. Even after pouring enough product that it should go past the trap, there was no magical dissolving of the clog. It is like the thick, slimy goo that you find with other slow drain products. I had high hopes for this stuff but only was disappointed.  Bought a two bottle pack and used up both to no avail.
