Review on TERAPUMP Power Water Fuel Transfer Battery Pump: Streamlined Auto-Stop Technology for Effortless Usage by Philip Brianne

I don't know who or why anyone would rate this pump negatively. My only criticism is that it took 3 weeks for delivery, but other than that it's freaking AMAZING! You place the main jack in a gas tank or can, turn on the power, and it immediately starts pumping and moving vertically up, almost at the flow rate you would expect fueling a car at a gas station. When you turn off the pump, the gas (or any other liquid) rushes back out of the pump, you pick up the pump, shake it a few times to knock out a few drops (I mean VERY few drops), and you're done finished. After reading some of the negative reviews and knowing that it runs on 2 D cell batteries I wasn't expecting much. However, I am amazed at how incredibly well it works. Buy it, you will either like it or LOVE it IMHO!
