HORRIBLE.  DOES NOT WORK, DOES NOT COOL but a few degrees
Doesn't work at all, the main unit, much less the attachments.  It simply doesn't get more than a few degrees cooler than room temperature, even after an hour.  And the attachments don't 'stick' or 'attach' to your body in any meaningful way, they're impossible to keep flush on your skin, so you get absolutely no cooling effect.  After 1 hour of continuous use, it felt WARM so I stuck my hand in the tank and it was indeed very WARM, NOT COOL.  I checked the setting, and yup, it was correct, the device just doesn't work.  The motor also make a fairly loud hum which will make your headache worse.  I suspect strongly the other reviewers work for the company that sells this product!
