- Product Review (submitted on June 6, 2012):
I recentliy bought one of these to drain my tank. It works great. It's very compact, the tube is thin and flexible, it will pump even if it's sucking up some air, and the out-flow tube has a metal end that keeps it from jumping out of whatever container it's in.
Until now, I've carried one of those inexpensive bulb pumps (the black bulb with the two clear tubes coming out of each end) and it has been a lifesaver. But it is now officially retired. The Cranky Pump is more compact, less messy, easier to use and, if necessary, can reach the nether regions of an odd-shaped tank...so it's good for draining a tank almost completely dry.
