Summary: This unit has been a disappointment from the beginning. I have tested it in two of our vehicles. Communication with the device is spotty - I am often told it is "asleep" when I know that it is not. Also, it reports erroneous locations, presumably arrived at during some kind of warmup period, but never corrects those locations after refining the fix. So the tracking map looks like the vehicle hopped all around the area. I cannot recommend this device.
Summary: I had the GTU 10 for about 2 weeks now. For about the last week, I was receiving NO notifications (low battery, unit powered off, enter/exit geofence, etc..). I just called Garmin tech support and and they told me the 'notification server' has been down for about a week and no real ETA. Pros: Price point (which includes one year of the basic service plan), compact product design with nice case. The web and iOS app are pretty good.
Summary: I have a Garmin Zumo for my motorcycle, so I chose the GTU-10 over the Spot tracker. I got the GTU-10 for 2 reasons. One was to keep on our dog, so we know where she is. The second was to take with me on motorcycle rides, so my wife could follow my trip. I've been testing it for a few weeks with our dog. I setup a geofence at our home.
Summary: Buon prodotto ma impreciso nella localizzazione. Dopo un anno diventa inutilizzabile se non si sottoscrive l'abbonamento standard, i costi raddoppiano se si aggiunge l'abbonamento delux per il rilevamento continuo. Durata batteria non eccezionale.
