The SHARP UW-X1-S, equipped with ultrasonic cleaning technology, is ideal for cleaning shirt collars, glasses, and small items. - Brand: SHARP - Model Name: UW-X1-S - Technology: SUPERSONIC washing technology - Accessories: Charger, cable, stand Thank you for viewing. I purchased this product about a year and a half ago to clean shirt collar stains, as it was highly praised on TV by a famous home appliance comedian. This is a model after a minor change to the product, and due to its popularity, I had to wait about six months for it to be in stock. I used it about 15 minutes total over three times and could feel the dirt coming off, but I realized it required some patience, so I am selling it. I stored it in its box for a while, but I have confirmed that it works, and it seems to be in good condition for use. (It's almost new.) Thank you.
