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.
My Garmin goes with me everywhere. I would recommend a Garmin to everyone. As someone with ADHD who forgets to charge their electronics, having a watch that only needs to be charged once in 8-10 days is absolutely amazing.
