Hello!
Yes, there are users of Samsung Smart Tag who are sharing their experiences in the forum.
Regarding your question about the location refresh rate, it depends on several factors such as the strength of the Bluetooth signal and the distance between the Smart Tag and your device. Typically, the location is refreshed every few minutes when the Smart Tag is within range of your device. However, if the Smart Tag is out of range, it may take longer for the location to be updated.
As for whether the Samsung Smart Tag is better or worse than the Apple AirTag, it really depends on your personal preferences and the ecosystem you are already part of. Both devices have similar features such as location tracking and Bluetooth connectivity but differ in terms of compatibility with different devices and operating systems. If you are already an Apple user, the AirTag might be more seamless for you. If you prefer Samsung devices, the Smart Tag might be a better fit.
