A:AnswerI could be wrong, but I do not believe that I have ever seen any that were not. So there's that. Carefully note that these did not fit my model, a result of my own error.
A:AnswerThe E series is obsolete. However, I found replacement heads at Best Buy Online and on ebay. There are third part replacement heads but they all seem to have poor reviews.
A:AnswerHello! The Philips Sonicare E Series toothbrush heads are compatible with the Essence Screw on toothbrush. The number provided would be your serial number. The other number above the "17" number would be your model number.
A:AnswerHello. I apologize I was looking for the box the toothbrush came in and the package the brush heads came in and I can’t find them. What I would do if I were you is call Phillips customer service and see if they can help you. I did look up the number for you.
