Review (4/5): 3 years of use and still going strong
My dentist wanted me to get an ultrasonic toothbrush but I did not want to pay a lot for it. I thought this one would be a great trial at less than $50. I like it and it has worked well for more than 3 years. I have not had problems with water, but then again I do not drown my toothbrushes with water.
