Bought PureMist FREE last night from Walgreens. First, I don't mind spending the $$ if something works. Instructions are horrible. Not enough information. Nothing about resetting device. "unplug, plug and push power on, quickly". Really, this is a "reset"? Literally, used it ONE time for 10 minutes. Followed all instructions and even had my doctor husband read instructions to make sure I was not omitting anything. Steam stopped coming out. Thought maybe it was a charging issue. Plugged it in and charged it for 3-hours. Unplugged the unit (as the scant directions that were included said the piece of junk, I mean, unit would not work unless it was unplugged.). Check the water reservoir. Turned device on and NOTHING. All that I get is a red line on the power switch that says it needs charging. Tried different outlet. NOTHING. What a colossal piece of JUNK. Good luck staying in business. I wonder if the fact they have three versions in a relatively short period of time means that the device has been consistently flawed since it was introduced. Save your money.
