Oral-B Oral B Sonic Complete Power Toothbrush (1 brush)

Good product
I bought one of these nearly 4 years ago and it's still charging, albeit the charging unit itself seems to be dying. Amazingly, I'm still using the original brush and it's still just like new. I used to have to replace my regular tooth brushes every 3-4 months. I bought a second one just in case the original charger finally fails. The only reason this unit didn't get five stars is that the charger is giving out before the battery. Charge lasts a little over a week.

Note that these units are actually dual voltage rather than the 110V they are labeled. They are actually made by Braun, and apparently labeled for the U.S.
