Review (1/5): waste of money, water got in the battery compartment and corroded
my first rechargeable sonicare stopped charging in 1.5 year, so I thought I will switch to AA battery operated sonicare. I thought I can use rechargeable AA battery, which would make the toothbrush last longer and it will be more green.well.. this toothbrush lasted only two annoying months. I constantly had to change battery due to corrosion. Parafilming didn't help either. going back to rechargeable expensive options. sometimes, I think the companies do this intentionally so that people switch to more expensive option. companies anyway are making money selling brush heads, why soil your reputation making bad product. Trust me, I 'll switch to another brand as soon as someone make something I like better. no brand loyalty here.
