Gill you might be the first person I’ve ever heard that said they don’t work!
There was one year that the skeeters were very large. Even on windy evenings they would find the downstream side of my head and land on my ear. They didn’t work real good under those conditions.
I’m not going to go into the story of the FL business that sent me a necklace that would repel skeeters. They were so bad that year if you started talking you would inhale them. I gained a lot of weight that year.
Fired up the TCell and within 5-10 minutes they were mostly gone. We even caught fish!
