I purchased the 528 backpack sprayer from Amazon outlet at a good discount. It was listed as like new. It arrived in an original slightly damaged box with no instructions. I wanted to use it to spray fruit trees. Like new should have been USED with an unknown chemical inside. Not wanting to damage my trees it took me two days of cleaning to remove the blue chemical that was inside. Beware of the product you buy that may affect YOU.

I don't really "rate" this product poorly, but it's wrong for wettable powders. I bought it to spray Surround WP, a finely ground clay "wettable powder" insect repellant popular with organic gardeners. I have used Surround for several years with a hand-held sprayer without problem. The SP leaked from the bottom first use so I returned it for replacement. The second one leaked also and lost ability to hold pressure after one use. This prompted research online as the reputation of these sprayers is good. I found something from a competitor, Solo, saying that wettable powders ruin "piston" pump sprayers but work fine with "diaphragm" pump sprayers (like the hand-held I've been using I'm guessing). Nothing in the SP documentation warns of this. SP offers an optional agitation kit that you have to order separately from the manufacturer and install yourself, but they don't say not to use the sprayer as-is with wettable powders, and I bet a power mixed thick (3 cups per gal) like Surround will still ruin the piston even with the kit. I ordered a more expensive SP0 that supposedly will work. On the up side, the Amazon return procedure was great.

My husband really likes this product, since he's the one doing the spraying, I'll have to take his word for it. No complaints.
