Title: No volume, weak spray, terrible.
Review: This product is not a pressurized 4 gallon sprayer. It works on a small pump (about 16 ounces) inside that quickly uses up its contents. Volume at sprayer is mininal compared to a pump up sprayer. It took forever to use up 4 gallons of product. At your store check the tiny orifice on the sprayer head compared to a pressure sprayer for a comparison how this will work. Used twice threw it in the garbage.
