I really wanted this product to work. Unfortunately poor design causes this unit to overheat easily. While medicine trays are intended to be disposable the ultrasonic process overheats the trays with more than one use and melts them. I would suggest changing the water for each successive treatment to mitigate. In addition, the cooling vent is placed in a way that a normal holing position will block the vent with a finger aggravating the heating issues all the more and making the unit too hot to hold. The rechargeable battery also stopped holding a charge after about 6 months just adding insult to injury.

Unfortunately, after spending too much for the unit in the first place I am forced to purchase a new compressor based unit now.
