Low quality appearance
I returned the Julia diffuser because in person the impression was of cheap plastic and low quality. I can't 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.
