So far have been quite happy with the Pebblebee Tag. The main usecase is due to the fact that my wife has Alzheimer's Disease, so searching for misplaced keys and wallet happens several times per week. Previously have tried Tile and Apple AirTag. Issue with both of these is the battery life is nowhere close to as promised, possibly because of how frequently we use them. Previously when the item had to be found frequently the tag had run out of battery and so couldn't connect. Also some of the AirTags had the problem that the battery compartment hatch would jam while replacing the battery. I had to use channel-locks and pliers one time. Kind of surprising that Apple doesn't find and fix these problems pre-production.
So we really like the fact that Pebblebee has a rechargeable battery which seems to be a much more robust solution. Also like that the battery change status shows up in the Apple "Find My" app. The alert sound seems to be a little louder with Pebblebee.
Thanks and keep up the good work,
Mike and Kathy
