I did buy some but have not used it yet. There are many products on the market for scent elimination or in the Primos case scent prevention. Truth be told NOTHING is fool proof Scent Blocker, Scent Shield, Primos XP, Scent LocK, etc... Does it help ---Yes, is it a fix all No. Bottom line is you have to play the wind as best you can or you will be busted. The biggest problem is with older mature animals that have been around the block a few times. If you don't play the wind correctly you probably won't even ever know they were there. My recent trip to ILL. taught me more than I ever knew about that darn nose and truth is you can't beat it you may think so but the answer is still no. In every area the deer and other animals have a tolerance level, cross it and game over. If a deer is coming to you care free and stops to look around he smelled you period. It is then that the animal decides what action it needs to take. All of this stuff is hype. It does work but no way near the claims they make. Always, Always, Always play the wind as best you can.
