I love the little retrieval tray that’s held to the lid by a magnet. There are also other magnets in the lid that only let it sit correctly to begin cleaning, or it won’t start. The UV light is a plus. It’s easy to use, holds a generous amount of water and runs at an ok noise level. The water gets surprisingly warm at the end of the 10-minute cleaning cycle; start with cold tap water. Reasonably priced👍🏻The power cord detaches from the unit for easy emptying and drying. It also effectively works as claimed-aligners show no signs of yellowing or buildup. Happy with this!
