Hey there guys, Tried out the new thermacell on my evening hunt last night and that thing is a miracle!! It is the first time I have ever been able to hunt in the afternoon in northwest Arkansas and not worry about being eaten alive. The pads are supposed to last for four hours, but mine turned white after a little over two, but other than that I wish they would have come out with this thing years ago!! Buy one, you won't regret it.
