Review title: Completely useless
Product review: This thing builds up VERY LITTLE air pressure, and what air pressure it builds up requires you to pump it down VERY fast. It does not build as you push down slowly, in fact it does nearly nothing if you push it down slowly. It barely makes good contact with the sink I'm trying to push a clog through, and if you're not careful and you pull it back up TRYING to make it work it squirts water all of you and random stuff from the top of the shaft. Complete crap.
