Does NOT work
I followed the instructions. I set it up. I added water and it won’t work. I did all the troubleshooting in the manual and still doesn’t work. I’m having a hard time getting in touch with the company. It’s taking them a while to get back to me. I’m afraid I might not be able to return the item within the required time.

Does work as advertised on the show
Doesn’t out a dent into the humidity in the room. I have 2 going full time and they don’t disperse enough moisture. Going to return both.
