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.
I love my wireless charger. I have an older iPhone with their stupid lightning port, no USB C for me. So instead I just use my wireless charger. No fuss with cables, put it on the pad to charge, pick it up to check something, put it back on. No fuss, no mess, perfection.
