What things do you have are surprisingly good / handy?

As I write this, I’m using a $10 foot massager from Temu that my wife bought. I thought it was totally stupid but it gets nightly use. We lie on the couch and just let it run.

Edit2: it looks like the LINGTENG one on Amazon - probably white labeled from same factory, nothing special about it but we like the simplicity.

What has anyone else found surprisingly useful?

Edit -

Here are some things that came in mind as I was walking around:

• Different type of mason jar lids from masontops for sprouting, cold press coffee, pouring spout for watering plants, etc.
• ifixit kit - originally used for phone fixing now used for prying random stuff - the Ifixit jimmy is really useful, and it’s great to have all tools in one place
• Shoegoo - originally used for shoe fixing now used for fixing bike parts - time to invest in a glue gun
• YouTube premium - I originally got a family plan so that my mom wouldn’t watch so many ads, but now it’s an integral part of my passive learning system - languages, guitar, sports, etc.
• hydrogen peroxide - I got it for wound disinfecting but it has only ever been used as a stain remover.
• cheap Muji mini umbrella - way more used than my fancy Davek
