This little dehumidifier works. I just changed to stars to 5. I use it in my bedroom and over a period of hours it takes about 1/2 inch of humidity out of the air. I empty it ever 2 or 3 days when there is almost an inch. Very easy on electricity It's easy  to use and the instructions are simple.  I have to sleep in a very dark room. You can turn off the multicolored fun lights but not the on/ off light which is blue.   It is very quiet and effective in small spaces and can be moved room to room very easily. Attractive in design. I would buy again.
