I save a bundle on scent elimination. I just bath in febreeze and hang a glade plug-in aroung my neck. Just teasin, I have to agree with you to an extent rack. Most if not all of these things do eventually wear off but I still like the scent elimination spray. I know it doest kill all the scent and the deer can still smell me but I think it cuts down on the odor and makes it a little tougher on the deer, but I always play the wind regardless. No matter how many gimmicks they come out with, nothing beats time and hard effort.
