For me, it’s an electric toothbrush. It doesn’t matter if you go with Sonicare or Oral-B, once you start using an electric toothbrush, regular toothbrushes don’t ever feel like they clean your teeth properly. The smooth plaque-free top layer of your teeth that you can feel after using an electric toothbrush can’t be replicated with a regular toothbrush.
Those are great !!
I had a combo unit that was all of that, AND a car jack!! It was VERY slow and there’s no way I’d go near a car using it as a Jack, but as an absolute emergency it was useful
