Review (5/5): Buying Extra Units for Travel
My wife and I bought 2 of these units a little more than 2 years ago. Love that gentle ultrasonic cleaning. They continue to work great.
Use basic common sense, as with all electronic appliances. Do need to keep dry; particularly the base where the battery and electronics are contained. Rinse brush and extension arm only; not the base/handle. Clean the attachment cavity each time battery is changed. We chose this model at the beginning, because we didn't want to have to buy new units when a rechargeable battery die; nor wait for charge, especially when we travel. We are buying another 2 units just to put in our traveling kit bags.
