I was really skeptical with the Ozonics at first, but after hunting with a buddy that had one, it made me a believer. I have hunted with one now for the past two seasons. As long as you still practice good scent control with washing clothes, showering, spraying down gear, it will give you that little bit of extra help needed to fool a deer's nose. I've had a lot less deer spook since I started using it. Some will still bust you if they hang out downwind for too long, but a lot of deer have walk through my scent stream and not busted me.
Glad to hear they honor our servicemen with a discount as well!
