Chipolo was mentioned in the Find My Device presentation during IO 23. Looking into them I found that they’re based in Slovenia. That puts them firmly under EU privacy and general regulation. If you’re in the market for such a device, this might not be a bad option. I’m currently using Tile but I pre-ordered Chipolo to try.
I might design and 3D print a card accessory to clip the One Point on. I know for Airtags you can buy them on Amazon for pretty cheap.
