Abelardo Lind's review of GPS Insight
Bottom line: it usually gives me a ping when I need it, but not reliably enough to trust during crunch time. I've been dispatching a 15-truck fleet in the Southwest for ten years and those occasional 1–3 hour GPS dropouts and slow support tickets are maddening, yet the trip playback and maintenance reminders have saved our skin a couple times - so I'm stuck using it, even if I grumble every outage.
