text: Seems to work, although the setup is less than intuitive. However, my main concern is the battery life. After two weeks, the app is showing that the battery needs replacing. I have ordered the new, free battery offered, but am concerned about the long term use if this device. Maybe this tracker sat for a long time before shipping. I hope so, but two weeks of battery life is a worry. UPDATE: The new battery solved the problem, but now the device is dead because the back fell off at some point and is lost. I’m disappointed. You might want to put a small piece of tape on your device to ensure that it doesn’t fall apart.
