I bought this sprayer for my 4qty-100ft rows of grapes and 5 fruit trees. I have used it three times now. Yesterday I used it to put a fire out in a large hollow ash tree located next to my burn pile. I burned a large pile of spring trimmings. An ash tree is located next to the fire pit and the inside of this previously burned, hollow tree caught fire, again. I usually use my 2gal pump sprayer but the wind kept the tree burning and burning. Next I tried my 4 gal backpack sprayer but got tired out after an hour. So I tried the new powered sprayer. I filled the 4gal tank 6 times and kept soaking the tree up to 25ft high where the top hole is located. Eventually I got enough water into it and the wind subsided for it to go out. ........Very powerful sprayer and easy to use. The hand truck is little chinsey but effective............. I sprayed the grapes and trees the day before with the flat nozzle and it worked really great. I was done in less than an hour and was not exhausted like when I used to use my backpack sprayer. I can't comment on long term durability but hope this tool lasts for many years. If your thinking about this tool for your property, my advice is order it!
