I had tried an earlier tracker that worked so well it became E-waste at the end of battery life. Basically, the radios weren’t there yet. A tag in the laundry basket could not be found or heard. Discovery of a tag left away from home relied on the general population running the tag app on their phones. Some did but the coverage in Norfolk, Virginia was truly sparse. Oh, and the battery life was about a month. BlueTooth Low Energy was not so low.
But I also watched the Apple announcement with some interest as I had just laundered one radio car key and cleverly hid the other in pants I’ve not worn for a while. The near death experience of the first key increased my interest in finding the second. I also have a couple of sets of Yubi Keys that unlock several important 2FA things. It would be really bad if they both went missing.
