I bought one a few years ago when I was remodeling my house to sell it. It worked beautifully. Plenty of power and great pressure. I bought an extra length of hose and a short whip hose and was able to reach long distances without having to relocate the pump. I was diligent about thoroughly flushing and rinsing the pump and the filter in the gun handle after each use and never had a problem.
The gun that came with it was very nice, but I preferred an older Graco professional gun that I had from a previous sprayer just for ergonomics. I sprayed around 40 gallons with it and then sold it when I downsized. It is a very capable sprayer and it folds up very compactly for storage. If I had to do it over, I'd buy it again as it is a very capable machine for the price.
