I refuse to share dh toothbrush as he doesn't rinse it properly, then leaves it lying in a puddle on the side of the basin 🤢. But I suspect those are the cheapest heads.
The action might be gentler, but if anything that would be a good thing for me.
So - AIBU, and should I go Frozen, Lion King or Spiderman??
