My first smartag
I'd been wanting to get trackers like this for a while.
The main drawback is the lack of interoperability with other networks: if you buy Samsung, it's only going to work with Samsung phones, not even with other Android phones. That said, this is true for most suppliers, such as Apple and its AirTags.
The module is fairly small and discreet, it seems robust and offers good battery life.
It takes just a few minutes to configure (less if you're used to doing it).
It can be used as a remote control (configurable action) to make the phone ring, it can also ring (to find it), and the VR guidance functionality is amazing and fairly reliable. I was right to take four!
