This is a tiny diffuser, yet one that packs a punch. It has a beautiful color changing scheme, and the white with wood look is really pretty. The build quality is excellent, there's no cheap plastic here, it is sturdy and well made. Despite the size, it's fairly effective in diffusing the oils, my bedroom smells good after about half hour or so. My only gripe with it is the lack of a timer to shut if ott after a few hours.
