I bought one last year and had several deer come in down wind. I had deer get close and stop to sniff but never spooked and several that never reacted at all. My moment was when I had two 4-5 year old ten points come out in the food plot 150 yards away and come straight to my stand down wind the whole time. By the time they feed and closed the distance it was to dark to shoot but they never knew I was there. Killed a really good 8 point that was down wind of me for at least 15 minutes for the 75 yards I could see him. Dr James Kroll did an experiment that showed the effectiveness of Ozonics. He has been a big scent control skeptic but really believes in it. I do use DDW wash and dryer sheets (used atsko and scent away as well). Then put clothes in bags. I do not take them out till I get out of my truck and get dressed in field and spray down everything. Also take scent free shower. The Ozonics is not a silver bullet that will cover up for big mistakes but is a great tool. It will get put to the test in 87 degree weather in our opener next Saturday.
