I think all these products are helpful but in the end make little difference. I use a few also. Cant hurt. Treestands do seem to help. My dad smells like an ashtray! He smokes alot. He hunts wind, no scent control, no camo, nothing but old orange vest and hat. He does very well. Hes bagged 6 or 7 bulls the last ten years and several deer. He stinks, doesnt hide and walks the wind very slowly. He is a rifle hunter so he doesnt need to be close but most kills have been within 150yards. He also has hawk eyes, lol. WIND...
