Review (5/5): just rcvd - will update review if necessary
so far so good. cycles thru 6 colors from what i can tell (blue-purple-white-red-yellow-green), if there's a 7th color i've yet to identify it. i use the intermittent mist mode (10seconds on and 10seconds off until water evaporates). been going for several hours so far. only complaint is that the plug is not your standard adapter but a usb plug w/ wall outlet attachment (this isn't a deal breaker and may not matter to some). all in all glad i took a chance and purchased this item.
