Title: Does not last
Review: A slow moving drain became less slow moving, but took a few blasts so it does work. It cannot handle serious clogs as the unit is small, and hence has limited power. However, after using the unit off and on for a month, the unit no longer holds the air pressure as I can hear a slow leak around the handle. When my neighbour first saw it he thought I had bought a toy, and I am inclined to agree. The good thing is it is inexpensive so two stars.
