Bought 2 of these for our Community Garden in November, so needless to say, they sat around unused for awhile. First time, one worked great! (Kept the other one in the box). Although it takes a lot of pumping to pressurize the container. Second time to use, couldn't get any pressure built up, no spray, nada. Reread the instructions, followed exactly, made sure all connections were tight, and still nothing. So pulled the other one out of the box and assembled. Well it didn't work no way no how, because it was missing the rubber ring on the pump! So I gave up and pulled out my 1 Gal HDX , and without an issue, it got the job done. Only wish the Garden Committee could get their money back.
