Are there any household gadgets you found unexpectedly useful after you'd gotten them? - Lemmy.World

I was thinking about how I missed having an indoor thermometer that measures humidity. It’s such a small specific thing, one I’d never think of getting unless pushed to it (which I was by one particularly dry winter). But I like having one now. What are your small, “random” or “junk drawer” type of gadgets that you actually use or like having around?
