1 year agoI’ve gone through at least 5 or so Philips sonicare brushes, and it’s almost universally the linkage to the brush head that fails. Seems like they can’t handle the vibration for more than a couple years.
The buttons aren’t terribly insulated from water/other crap too, but honestly I’ve never had them fail, so it’s certainly not that huge of a concern
There’s nothing technically stopping you from building an android smartphone just the way you like. In fact, there’s extreme modding folks that do things like already. What we really lack is a future-proofed connector standard for component connectivity that just works.
