Market grower from PA wrote (July 16, 2015):

Bought one for spraying foliar fertilizers, was very happy, it took the abuse of daily dispersal of three tanks of liquid for 50 days and counting. I bought another one for herbicides.

5 Stars Very good product.

This sprayer works very good. I would recommend it. The metal sprayer tip is the best.
