I enjoyed my aroma ace diffuser (a present from a friend) until I accidentally tipped it over and it didnt perform the same. I stored it for a year or so and brought it out to send back to the factory for repair/cleaning. As it was a gift, I didn't have a receipt, but I did have the original box it came in. I paid a small (reasonable) fee to have them clean and replace needed parts, and Voila! I have a like new machine that performs like I remember it. Diffuser World notified me via email every step of the way. I received it back within a week. I highly recommend this diffuser and this company. No complaints at all. 5 stars!
