18V ONE+™ ½ Gallon Chemical Fogger/Mister WITH 2AH BATTERY & CHARGER
18V ONE+ 1/2 Gallon Chemical Fogger/Mister is rated 4.3 out of 5 by 497.
Rated 1 out of 5 by from Unit leaks poor Quality I bought the Ryobi Fogger and used it three times and it started leaking everywhere. Really dissapointed. Based upon the other reviews this looks like a chronic problem.

Rated 4 out of 5 by from Works well for small - medium size areas Note: you tube reviews appear to sometimes have clogged machines. Observe recommended solutions. Black Fogg appears to work well for me. Observe fill line. I have had propane foggers and industrial models. This is more directional than a small propane which is good but the propane mist is finer of course. It goes without saying you want to use the downwind to avoid backsprayz. Spray and leave area for awhile. I'm going to experiment with some less expensive solutions also and might update although the black flag is pretty inexpensive. Quick, simple, works well of directions are followed.

Rated 3 out of 5 by from Sprays great, but leaks and uses battery too fast Have used five times so far, does a great job of spraying a fine mist. Cons: uses battery fast, a 2ah battery lasts about 12 mins, or about 1/4 of a tank of liquid. Will only spray if horizontal or angled upwards, any other angle and stops spraying. Leaks liquid out the back, all over battery

Rated 1 out of 5 by from Broke in a year Bought and quit working in about a year. Fell out side of the 3 year warranty so my only option was to drive over an hour to a authorized repair and would fix if they deemed it was manufacturer defect, if not I would have to pay.
