GMMAT.....I broke down and bought one last year to use here in MD where the skeeters can be thick in the early season. It definitely works and they are a snap to use (no learning curve) but where to put it in your treestand can become a bit of an issue. It has to lay flat with the grill portion facing up. It also puts out a little bit of heat. I duct taped mine to the base of my climber off to the side to keep it out of the way as much as possible.
