It's definitely small and inexpensive, but you get what you pay for. It's quite loud/hissing, more than I thought it would be. I thought since it has an auto shut off feature it would also turn on automatically but it doesn't. That was the main reason I bought it too, well, back to the drawing board. Edit: I disassembled it to see the innards, it's not much, see picture.
