this review title is: low quality appearance and the content is: i returned the julia diffuser because in person the impression was of cheap plastic and low quality i cannot say how it performs my problem was with the aesthetic in contrast i have an alpha aroma essential oil diffuser which is also plastic but has a much nicer finish my suggestion to the folks at stadler would be to look into the flat black finish of the alpha aroma diffuser.there are other information for this review, one is this reviewer did purchase it and the other is 2 people think this review is helpful.
