This is a product I received last year as a return gift for my hometown tax donation. The SHARP UW-X1-S uses ultrasonic cleaning technology, removing dirt quickly with 38,000 ultrasonic vibrations. [Product Details] • Brand: SHARP • Model: UW-X1-S • Cleaning Technology: Ultrasonic cleaning • Function: 38,000 ultrasonic vibrations • Accessories: Charger, USB cable, adapter I used it a few times at first, and the main unit has a slight feeling of use associated with normal use. There is some deterioration in the adapter, but it can be used without any problems with charging and operation. I haven't had a chance to use it recently, so I'm putting it up for sale while it's still in good condition. It's a popular product. Charging and operation have been confirmed. Please refrain from purchasing if you are concerned about fine details, as this is a personal inspection. I have never had any trouble with transactions so far. *Please be sure to check the profile before purchasing.
