I have personally used heaters for about 12 years. I have had no problems with any scent. Everyone I hunt with uses them also.

I am located in tx, so most everyone has a blind of some sort. I personally use two or three at a time. Call me what you want, but I will not get cold. HA HA

You may get busted on the nice red or orange glow when it is dark, but I wouldnt worry too much about that either.

Technology is GREAT !!!!
