I have one... I am not sure how much it has helped me, and I seriously don' t think it is a Cure all... and the slogan is BS " Forget the wind, just hunt" NO WAY... But it is just another thing to add to your collection of things to fool that Monster Whitetail...Main thing I think is to still use all your scent free practices and don' t think just cause you have this Majic suit you can get away without using cover scent, and Scent Eliminator...
