This is the piezo disc (metal disc for ultrasonic humidification) only, for the Dyson AM10 humidifier. *Cords and base are not included. I purchased this new, thinking the disc was the problem for reduced humidification, and used it only once. However, the cause turned out to be another part. Therefore, the disc itself is still in good condition. Number of uses: Only 1 time Condition: Operation confirmed, no noticeable stains Compatible models: Dyson AM10 Can be used for maintenance or as a spare. Thank you for looking.
