The Zima Dental pod is the ultimate oral appliance cleaner. Ultrasonic technology designed to eliminate bacteria, viruses and pathogens. Easy to use, refill and clean. Used this one time. I’m just not disciplined enough! Great for kid’s retainers when they are not so great at cleaning them. Comes with the entire starter kit (139.99), plus the additional premium sterilizing tablets that I purchased separately (17.99)
