#Google rolled out their device finding network a few years ago. It's still utterly useless.

I put an #Airtag, a Samsung Smarttag and a #Chipolo Spot in the side pocket of my car.

I currently have a Samsung phone with Google's Find system set to find anywhere. Wife has an #iphone

The Airtag updates and is traceable pretty much everywhere. The Samsung Smarttag is pretty much similar, sometimes it's position is half an hour out of date, but a few refreshes later it pops up.

The Chipolo running Googles Network is bad. It hasn't seen the tracker since 2nd June. The tracker is in the car which is 3 feet away from me. Last reported position is at work, 50 miles away. I, along with the tracker visited the largest city in the country on the 4th June, where the car sat in a highly populated area for 3 hours.
The actual Cipolo is still transmitting, because I can see it in #homeassistant

Tldr; don't buy a Bluetooth tracker that relies on Google Find My network, and expect to be able yo find your thing.
