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 found gas struggles to do low temps too, minimum power in the smallest ring is still too hot for rice unless you want to keep stirring it. Induction I just get it to a boil then leave it on low and it won’t burn without stirring and leave it for 15 mins.
