Product review (1 stars): BIG disappointment
The product arrived on time, but it doesn't work very well. We feel that we can't trust the humidity level displays.  We have put it on top of our humidifier and the humidity level does not go up, we've taken it into the bathroom and left it in there while the shower is running - barely moves. We are not happy with the device and would return it, but the company doesn't provide any information for returns. Probably just a waste of money.
