After purchasing I had high expectations for this unit. Initially because of the professional handle and Tips, I thought this would be a more powerful sprayer. I'm reviewing it just below professional grade. While the spray is solid it is not what I would call a powerful stream. But then again for 200.00 dollars what does one expect. It is indeed a good solid unit and will deliver product effectively for small and mid size projects. You might want to consider changing out the tips and finding one that delivers the kind of spray that will work for you. This you will have to do after you get the unit and try it out on your specific purpose. at approx 40- 60 PSI it gets small and mid-size jobs done nicely. Flower beds and general spraying is what this is for. With the 4 gal tank it is just the right size/flow to get 4 gals of product down. I'm ordering a 100psi plus unit for my larger applications. If you need sprayer to spray fungicides, insecticides and liquid fertilizers on flower beds and small med size plants and ground cover this sprayer is perfect. I will say this about the design, It will make you look like a "Storm Trooper" and I say that in a nice way. It is just a nice looking uint, you will not look "dorky" with this back pack on.. Green Touch is also a very good seller and responsive to my contact with the company. For the money it's a good value sprayer. Would recommend. Gman
