I bought one, used in a ground blind and had a doe crossing right to left about 60 yards out completely oblivious of me without a worry in the world. As soon as she crossed into my wind channel, an abrupt stop and 180 degree turn around and now on high alert and retreated from where she came. Absolutely made zero difference from my one observation. I sold it to someone on here who reported back they loved it. To each his own, but not for me. Keep it simple and hunt the wind....
I ran a bead of silicone on every board before screwing them together. I then siliconed all the seams inside and out. I bought the best window/door weatherstripping I could and ran that around entire door. I put a swivel latch on door and the thing is air tight! When I was done the inside smelled like silicone bad!!!!!! After an hour of running the ozone generator the silicone smell was gone and never returned.
Whether they work or not may be a debate for someone else but I simply do not want to pack something else to a tree along with all the other gear that I have. I have been trying to minimize, not increase the load.
I just broke down and bought one. I've got a lot of hogs that will give it a run for it's money. Let you guys know.
