These units are an advertising gimmick, that sell the same device for between $20 to $150. There are even units that Hollywood stars are selling in TV ads for even more with monthly subscriptions that come with miracle potions for your health and well being. I bought the device as an air freshener and I bought this unit used in the video because it was the cheapest one. The , so called, miracle oils that are sold along with it were the cheapest also. I need to try and find one that smells the best for me because to maintain their illusion that these help your health and well being, some of them have a mild medicinal scent to them, like menthol or mentholatum. All a bunch of nonsense as far as I'm concerned. I am happy with my room deoderizer and once I find a non medicinal scent I like, I will be happy.
