I’ve used Chipolo tags and they work well enough, but keep in mind that virtually all Bluetooth tracking tags - including Chipolo - use either Google or Apple’s tracking network so it’s hard to divest yourself of them entirely.

My experience of Chipolo tags that use Google’s network is that they work just as well the Pixel tag and AirTag for finding objects nearby, but because there are so many more Android Things than iThings about both Chipolo and Pixel tags are way better than AirTags for tracking down things in the wild.
