Harbor freight backpack sprayer. A nozzle of the spray nozzle leak so bad I had to rebuild it with parts I had from another sprayer. Then when I filled it on a level surface, it tipped over and spelled out 4 gallons of expensive weed spray. Every other sprayer I had Between the base and the pump handle would hold the sprayer level on a surface until U could fill it. Not this one. And you do have to use that little cross strap to tie the two shoulder straps together. The sprayer is so wide that if you don’t use it one of your shoulder straps keep flopping loose and falling off your shoulder.A whole lot of trouble for $49 sprayer never pays to go cheap.
