I'm hoping for the best ... time will tell. We tried the Thermacell a while back and it seemed to work "okay". It worked best if I were in a deer stand or turkey hunting where I was in one spot and motionless for the most part. But when we'd be on the pool deck or front porch ... we'd normally be moving around (BBQ'ing and going from house to deck, etc) ..... it didn't work all that well. It also didn't work worth a squat if there was a breeze, but luckily, the breeze would also cut down on the number of mosquitoes anyway. The thing I like about this new deal is that it KILLS those little bastages! I'll take that over a repellent any day. But again, if you're hiking, camping or in a hunting stand, the Thermacell might be a better choice. The jury is still out, I'm waiting to see how this thing works. We've had so much rain lately, we really haven't spent much time outside.
