It works great!!!! I will always use it. I dont think it takes 100% of your scent away, but it takes enough away that the deer dont spook. The only thing with it is that you have to re-activate it a bunch depending on how much you use it. I re-activate mine once a week and my facemask every 3 days. 2008 was the first year I went 100% scent-lok and did not get busted at all! Great product!
