Rated 2 out of 5 by from Leaky product I bought this about 6 months ago and I used it regularly as instructions stated. However it started leaking terribly I've not been able to use my fogger in the last 2 months. Can somebody please explain to me why it is leaking so bad.

Rated 4 out of 5 by from Overpowered fogger Today I used my fogger mister and it really pumped out the liquid. It's great, even if it is noisy.

Rated 4 out of 5 by from easy to use First off, i love ryobi tools. I got this tool to get rid of bugs at commercial building that has an outdoor deck. I filled up the ryobi to the line and added the concentrate. plugged in battery and went to work. i only held the lever for 10 seconds max and made sure to keep the tool level. not tilting it too much. So far i dont have any problems.

Rated 4 out of 5 by from Works like it should This is a great little tool. It is loud inside but you can barely recognize that outside. I'm excited to use it for my fruit trees.
