Great overall for mosquitoes
I didn't realize I needed to set it up from the box, but that was still easy to do by following the included instructions. It flows wells with the variable chemical nozzle, as well as the ball valve on the arm when the lowest setting is still too much chemical. I doubt I'll use it for dry products, but I do like the sprayer for mosquito misting. It is a little slow on the power response, but gives great flow overall. I can't complain for only $400; and they didn't charge for two day air shipping, either! Worth the price.
