Query: Haier Ultrasonic Cleaner

For cleaning dentures my dentist suggested an ultrasonic cleaner (he said that's what they use) so I went online to Amazon and after searching several, I bought the Haier Ultrasonic Cleaner. I wanted it specifically for cleaning dentures ... I use it once a week and what a difference!! It also cleans jewelry very well, even watches! It's definitely worth the money!
