Have not tried this product, but years back tried an Alpine air purifier someone was trying to sell me. Fried up some smelt with windows and doors closed, turned on the machine, and by morning there was no trace of smell. But that was a unit that ran on 120V of house current in a closed area. These units are in the open running on batteries. I could see them working quite well in a closed ground blind. I have some doubts about them working that well in a tree stand. The ozone generated (O3) oxidizes the stink molecules (organics) and breaks them apart so they no longer stink since they have been chemically torn apart into smaller molecules. The home model I had would give you headaches and a sore throat when it ran (since it was working on your throat lining), but as soon as it was turned off the O3 quickly reacted and turned back into normal O2. I sort of doubt this smaller version for hunting would give you headaches, but it is possible (and not something they will tell you about in advance). It would be a nice thing to turn on in my tiny office overnight when not in use in a closed ground blind. If I had an extra $300 laying around
maybe I would give it a try. Or perhaps borrow one from Valentine since I am sure he will purchase 3 or 4 of them
