Review (5/5): Seems to work as well as my previous Oral-B toothbrushes
This is my 3rd or 4th Oral-B toothbrush. They seem to last a year or two, sometimes longer. Unfortunately this one uses a different charging unit than the previous two toothbrushes, so I no longer have a spare to set up at my parents' house. Other changes over the years include the 2-minute timer (which I don't like), and the lack of a light on the toothbrush to indicate that it's still charging. But it's just a toothbrush so I can live with these changes.
