Rated 1 out of 5 by from 1/2 Gal Chem Fogger Just received this fogger which I ordered online from Home Depot. I filled with tap water to test. And I'm quite disappointed in its performance or rather the lack thereof. Pulled the trigger and it only blows a mist so week you can't see it. I had to put my hand in front of it to confirm if any water was being blown. And that's the only way I confirmed that it was blowing some liquid. But as I stated, it was a fine mist even though there was good air volume. Plus, the mist that it was blowing was intermittent. Didn't expect this small unit to perform as well as my existing backpak fogger, but I did expect it to fog. I'm returning.

Rated 1 out of 5 by from Don't waste your money! Have purchased 3 of these machines over the past few years. Every single one works for a handful of times, then starts to leak so bad the liquid just pours from the machine onto the ground. Home Depot talked us into buying the warranty on this item which in the end we found out, it was useless. It doesn't replace the item. We put in a claim with Home Depot weeks ago and have yet to hear back from them. Complete junk and waste of money.

Rated 1 out of 5 by from Complete crap I was so excited to get this product…charge the battery, fill it with insecticide and I am pumped to begin killing mosquitoes. Fire it up and it just blows air, there is not fog or anything getting any kind of mist unless I shook the unit. So disappointed and have mosquito bites to prove it !
