Query: Great Quality Sprayer

I first purchased a Stanley back pack sprayer from Sam's Club which worked very poor, had to return and purchased this one for twice the price. It was well worth the extra money, it pumps very easy and produces a nice even flow spray. You can spray out the 4 gallons in about 15 minutes, with great coverage. In comparison to the Stanley the quality is quite superb, like the pump handle itself, the straps, better washer with screen in the sprayer tip and also the parts on this sprayer are made of HDPE, for long lasting. It is also USA made.
