I just contacted them using this information and the woman was extremely helpful and polite. My toothbrush broke and I have been very upset about it because I love it so much and because it was so expensive. They are sending me a replacement and also a return shipping label so I can send my broken brush back to them.
Excellent customer service and they fixed my issue on the first try and within 10 minutes. The only disappointing aspect is the new toothbrush will only be covered under the remaining time left on my original warranty. So if the replacement breaks, I'll have to buy a new one.
As far as the customer service goes, I couldn't have asked for anything better. This is the exact opposite of Comcast/Xfinity customer service which is the ABSOLUTE WORST! Yay for Sonicare!
