I use this to track my ebike. I've previously tried tracking with a Tile and the Samsung GPS tracker and both were trash compared to this.Great:- Battery life really is 1month+ when set to update every 30 min- Reliable. The tracker hasn't crashed and always connects over bluetooth when I'm near- Small and hideable- Affordable/simple subscription ($30 a year, don't have to worry bout a sim)- Uses LTE-M instead of deteriorating GSM networkBad:- You don't know when you have service. The tracker relies on ATT LTE-M network to communicate its location. When there isn't service, it can't. Think places like a concrete parking garage.- Irregular location reporting. Sometimes It doesn't report it's location for 30+ minutes even while on every 5 minutes. This is OK because it always seems to recover and report it location eventually, but what happens in the interim?- I'd prefer a square instead of a rectangle
