Novel but design flaw
It looks good and I have a frog humidifer by the same company and it works great.  The orange has a design flaw, like many of the other reviews, within an hour, it stops and the light turns red (no more water) but there is plenty of water.  There is a slope where the water from the holding tank to the part where it puts the water in the air, is too shallow so water doesn't flow.  If you prop the orange on one side so the slope is greater, than you won't have an issue.  I still continue to use it.
