I don't use it simply because I think it is too expensive. Without it so far this season I have shot 4 deer with my bow. I have watched on two seperate occasions 4 deer bed down within 35 yds of me (they were there over an hour each). I have also had smaller bucks and shooter bucks (after my buck tag was filled) walk around and stay in shooting range for over 15 minutes. I am not going to say that the scentlock stuff is a waste of money but I have found that it is not necessary for me.
