GL300 glitches
The first unit I received was defective. Very weak cellular section. Took hours to connect, even in strong cell areas. Poor connection. Often lagged an hour or more before reporting movement. Often would miss an entire trip. Replacement unit much better. But still experiencing occasional lag times of 15 minutes plus. And occasional missed trip not logged at all.
Customer service fair. No live real time assistance. Emails often not answered promptly. Once communication established personnel are helpful and friendly.
