Title: Horrible design
Product review: I'm giving this 1 star because there is no option for zero stars. The idea is simple and good but the pump design is pathetic. I have a background that deals in this type of mechanics and they failed completely in making this usable. The first attempt drained brand new batteries in less than 5 min if operation. Second attempt the pump could not generate enough force to make a full trickle (line fully bled of air). Third attempt the switch started to fail... It's now in my truck waiting to be returned. Don't waste your time.
