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.
Someone I know (who isn’t close to me geographically) said their laptop just broke and now they only have their phone… I wish I could get to them. I have like six computers waiting to be used for stuff, the rest of them I’m playing with/learning with!
