Have the Garmin GTU 10 purchased to monitor my "Runaway" -Hundes. Unfortunately, the device does not deliver what is promised. In particular, the battery life is much shorter than indicated. Even with the setting with the rarest messages needs to be recharged every 2-3 days. Bad is that the battery state of charge can not be read on the device itself, but only via the Internet through the account at Garmin. This is also the second significant weakness: it lasts and lasts and lasts ..... until the GTU at last, is sometimes pinpointed only after 30-45 minutes (of course in the open with no visual obstruction to the satellites), and then also still very patchy , The app for Android phones is not exactly a hit: for emergencies just too slow and cumbersome, too bad ..... Overall, not very picures, but lack of affordable alternative for me, unfortunately, the only solution.
