So, about the TrackRs...

I will note that through all of the many comments about the TrackRs, the issue of battery life was a common thread, but the batteries were always replaceable. One of the competitors for TrackR is Tile, and their “Tile Sticker” model has a non-replaceable battery - and they still want $55 for a pair of them, when that battery is designed to last no more than a year.

And it doesn’t last more than a year.

Y’know, I’m almost sad that I never ended up with any TrackRs. Not quite, mind you, but almost.
