i personally think this is a gimmmick. ive tried it with no luck. ive tried a lot of other stuff too. to be honest the only stuff ill buy from is paul pollicks deer lures. great stuff. will not spook deer. u name it they have it. i use preorbital gland scent, interdigital scent and tarsal scent from them. the stuff works u will not be wasting your money. they are based out of pennsylvania.
