I got some of those Chipolo trackers shown in the photo. So far I’m pretty disappointed. Based on the locations being reported, I’m pretty sure my phone is the only one in my city working on the Find my Device system, and even that is intermittent. For example, I’ve left my bike, which has a Chipolo tracker hidden on it, in public places such as a busy train station. After two days on the station platform - with goodness knows how many Android phones passing by - the bike is still showing as being at home in my garage. Like, it didn’t even get logged on my own phone as I cycled to the station and left the bike and tracker there. The system really isn’t up to speed yet
I personally disabled the feature on my phone when it popped up as available. I don’t have much of an interest in contributing to a weird surveillance network.
