Great. Super quiet. Various options for light colours or one setting rolls the colours from one to next all night. I love that it splits the most through the dual nozzle at the top which allows it to disperse better and not pile up and land on the ground. We use it for a 6mx6m size bedroom from 8pm to 8 am and one full lasts 2 nights at full blast. Arrived quickly in perfect packaging. (This is the second one I purchase which replaced the first one. First lasted me two years but I blame my tap water for calcification build up. First one had a brighter light than the second, though I like the second more I prefer the dimmer).
