Good product for price
Good product. Well-made. Good backpack/carrying functionality. Wish the pump handle was a bit longer. (I'm 6'4".) One of the nozzle storage latches already busted off, but overall very pleased that I purchased this product.

Stanley backpack sprayer
I have always sworn by Solo sprayers but moved to Oklahoma recently and needed a sprayer now.. My Solo was still at my other house 2100 miles away.. Never thought I would say this but I would buy next time a Stanley over Solo for it is a comfortable sprayer that does a great job.. So far I have only sprayed weeds and about an acre plus of my lawn but I am sold on it

Good Sprayer
Well built for the price with excellent documentation booklet and well designed construction, good ergonomics, as comfortable as 4 gallons on one's back can be. Adjustable pressure and spray patterns.
I experienced a solvable problem in that, after a few hours of use, 2 bolts connecting the handle to the pump worked themselves loose and stipped the threads of their socket. The specs on the bolt (allen head 7/16" at 20 pitch) were odd enough that my well stocked country hardware store couldn't match them. I improvised with smaller bolts and nuts and added a little thread lock goop. And was soon back wreaking death among the phragmites.

Left something to be desired
My issue with this sprayer is in the compression fitting where the hose connects with the sprayer wand. It failed after only a couple of hours use. I tried cutting off the flared hose to start over only to run into the same problem again. I'm not one to return things if I can't make them better. I dropped the whole plastic compression fitting idea and went with a brass hose bib and hose clamp. A much smarter way to go in my opinion. No more problems. Stanley should spend the little bit extra on a metal fitting and clamp to alleviate customer dissatisfaction.

Very pleased
Great service, and product is fantastic, wish I had found

it earlier.
