It is a piece of dog doo. It is a waste of time-buy a good one. I have an Appollo, if you do not want to spend the bigger money, buy the Porter Cable that attaches to an air compressor (you will get a lot of bounce back).
The $80 sprayer works, it just does not work well-I took mine back-it clogged up right away (the plastic and metal combination does not go together well).
