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.
carbiners and keyrings. they are hella useful although while you don’t need to get climbing grade you don’t want the cheapest level of consumer crap. The spot bot is great if its still the same setup. basically it just automatically rotates a scrubbrush with soapy water and sucks it back up. It basically cleans a spot like you got on your hands and knees with a bucket and scrubbrush to clean it. Very small area but thoroughly cleaned. crappy unbrella hats. its nice to keep the rain off while being able to use both hands. folding kitchen step stool. the larger kind with two levels, a magna cart, thumb drives, steamdeck, man likely lots of other things.
