Review (5/5): Absolutely love it.  This one is different
Many of the other diffusers you see a heavy stream of vapor. This one because the output port is semi blocked you get a ton of scent without alot of water vapor you can still see vapor but it shots it very high. I was always concerned about the amount of vapor coming out of the other ones so I wouldn't place them on wood. This one should be fine on wood. Great diffuser and very cool looking! It doesn't do timed intervals but reservoir still lasts a very long time.
