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.
Mosquito magnet
Expensive to buy. Expensive and fiddly to run. But boy, does it totally destroy mosquito populations!
Especially if you start it up from the moment of Spring thaw… catch the very first females as they reach reproductive maturity. Breaks the population cycle. Love it.
