A:AnswerHello! Yes, the 2 series brush heads are compatible with the Philips Sonicare Protectiveclean toothbrush. Any click on brush heads are compatible with your toothbrush.
A:AnswerI did frequently clean and dry my old one but there were places very hard to access where the moisture was being retained.
I'm not really asking how to clean it. I'm asking if the design has been improved, where their aren't these deep grooges, crevises, and lips that can't be cleaned and dried fully. Does that make sense?
A:AnswerHello! The toothbrush shaft appears to be loose and making the noise. We recommend contacting Philips Sonicare in regards to your warranty at 800-682-7664.
