Alright my friends. I joined the club last week. Fired up the thermacell for the first time last night out on the patio and got it going right now with the fire pit. Jury is still out. Do I notice a difference/think it helps? Yes. No bugs in a 15x15 area, I’d have to say no. As a matter of fact, I just sprayed some bug spray b/c those little small black mosquitoes were wearing me out. Don’t shoot me, just giving my early evaluation. Maybe it’s something I’m doing wrong?
