I had two Sonicare brushes that stopped working within a couple months of each other, these units were about 3 years old.I had the wonderful opportunity to be helped by Carlsonkane, a Customer Experience Specialist. He looked up my info, I sent him a picture of the defective units and he promptly initiated a replacement for both.Carlson was clear, concerned, articulate, understood the product issue and detailed out how and when the replacements would be sent.I never expected replacements, I was only trying to bring a potential product issue to Philips awareness.Unfortunately I did not stay on the phone to take the survey as I should have but want to thank Philips, and especially Carlsonkane, for the help and professional that was extended to me during our conversation.
