Good for the price
There's a lot to like here. Muji aroma diffuser ultrasonic is a refined option that may take a few hours to bloom, but once it does, it's a joy. Worth the patience.

Better than expected
I bought this on a recommendation and it lived up to it. Muji aroma diffuser ultrasonic burns evenly, throws a generous scent and feels considered from the moment it arrives. I'll be replacing it when it's gone.
