Harvest King/Chapin, Professional/Deluxe, 4 Gallon Backpack Poly Sprayer 61705
Product Review (submitted on June 11, 2013):
UPS brought it faster than I thought! Out of the box, looks to be well made. Easy to put into use. Filled it with water first. Chemicals are not cheap. No leaks. 4 pumps and I had pressure. I am pleased. Down side, the straps are narrow. Overall I like it. I have used 3 gallons of weed killer so far. No leaks. Tech Tip, drain unused chemical into a bottle, Rinse the unit out, including the wand, hang it upside down to dry. Should last for years. I am very happy with this sprayer.
