More expensive because they couldn't annoy you into buying as many brush heads? It's sort of the subscription vs. software license debate all over again, but in our mouths... I will admit to using my brush heads past the time when Philips 'helpfully' starts nagging me to replace them, and it was sort of satisfying to see this reset work. It also got me looking around and I see people pop the NFC rings loose from old heads to reuse them as NFC tags, which is fun, I will have to harvest a few of those (I do eventually retire mine and use them for scrubbing etc.)
