Review (1/5): Horrible Product I Ever Used!
Bought two toothbrushes for my wife and I, and two packages of replacement heads. Mine crippled soon due to the water leakage to the battery compartment, and water leakage also caused odor formed from the base compartment of the brush. Even worse, I was forced to buy a new set because we still have too many replacement head to use!
The must be tons of stupid engineers at Philips Sonicare, and I will definitely switch to other brands!
