I sat down on my couch after the guy in the back house got the vaporizer to work - both of them - so I'm keeping both. The cheaper one is like the one I used to have, but VERY noisy. Anyway, after turning it off after fifteen minutes, I sat on my couch like so much fish with remote in hand, looked for something to watch and before I could even scroll down I went out like a light for three HOURS.
