Lots of reviews, I'll just add mine to the pile. I think it's great. We're in Florida. We have lots of bugs.. Mosquitoes, moths, flies, gnats. And we see the evidence of them every night when we turn on the security light next to the front door. Since installing the Flowtron, the cloud of flying insects has diminished considerably, or, at the very least, relocated to the unit. And I can tell by the zap... zap... zap... that it's working.
