Gosh, it's great!
I just ordered my 4th bottle of this oil, to use in combination with US Organic's Atlas Cedarwood. It's subjective, of course, but to me, the fragrance is absolutely fantastic when I use a cold diffuser.  (Don't forget that essential oils are so concentrated that they can be unpleasant, or even unrecognizable, until they are diffused.  I think this is particularly true of rosemary oil).
