    Replacement electric toothbrush heads run on the same scheme as disposable razors with high margins and vendor lock in. I’ve also seen vendors (Phillips) change the design to force you to buy another base station/brush.

      Also you can’t replace the battery. So if you electric brush is dead, you will need to replace the whole thing.
