Nice sprayer / needs better padding in harness

Works very well, you can pretty much get it completely empty without any effort and I really like the pump handle to pressurize it. The backpack harness on the other hand offers minimal support and is almost completely useless with 33 lbs of water (4 gallon load) + the weight of the sprayer. I'll end up getting something aftermarket as the harness is pretty much for the trash.
