Temperamental about the water level but seems to work on regular setting
I found quickly that it doesn't seem to like any water level.  If you hit the main button for the initial boost (blue light), it will run for a minute and then stop and flash red telling you the water levels are off.  But no matter what level you put it, it won't stay in boost mode at all.  I found it easier to just set it to the regular (green light) standard mode and that won't happen.  I was surprised that this doesn't do any kind of auto-shutoff.  I left it on one evening and forgot to turn it off.  It was still running the next morning.  It does what it should for the price.  I have only had it dispense "smoke" steam one time. It has never done it again since. But the smell is still potent even if not steaming.
