Interesting and useful device
I got this because not only did I want a room air freshener, but I am very interested in cold plasma technology which I believe is going to revolutionize medicine, environmental clean-up, sanitation among other things. Who knows, maybe it even gets rid of ghosts! It is small but sturdy and well-made, was well-packaged in a strong little box,  and seems to work. I have a stuffy room in my house and after putting it in there for around 15 minutes, the air is noticeably cleaner. I still haven't quite figured out the best way to charge and then use it, it does take a couple hours to charge, then runs 3 to 4 hours before it needs charging again. I don't think it's designed to run continuously though, instead it clears air in a room or car fairly quickly. It could be useful to bring somewhere with you where the air might be bad, or there is a fear of germs in the air. Anyway it's an interesting device, it takes a while to really figure out how to use it and discover if it may have additional applications which I suspect it does. It does come with directions in English, though I wish it was a little more indepth.
