Like everything else over the years I've collected one Fitbit and two Amazfit trackers, meaning three different little magnetic thingies. At least the Amazfit devices use a standard 20 or 22mm watch band. The Fitbit has a proprietary attachment that third party providers seem to have a problem with. The current Amazfit only comes with the magnetic puck that has a USB-C port; bring your own wall wart and cable.
