Review (5/5): Great Alternative to Rechargeable Sonicares
My family has been using Sonicares toothbrushes for over 10 years. Until recently we were using the more expensive, rechargeable varieties. These AA battery powered units clean just as well and pair very nicely with rechargeable AA batteries. Nice to know we won't have any problems or dead batteries during travel as well.
As other's indicated, we've been careful with water and the battery seal. So far so good!
