this little guy actually works really well.  I have a larger dehumidifier so am familiar with how they should work. I got this to have in bedroom when it's especially humid.  I had tried another small option and it was useless.  This works same as my larger unit, just on a smaller scale.  It does make noise, but I wear earplugs and it's fine.  I also keep it on the higher setting so it will work all night.  there is a lower setting that brings the noise level down a lot, but not sure how much it would do.  I'll try it one of these days.  This is a good quality item and does perform just as described.
