Very happy
Went on a group ride in the back woods with 10 other guys, some with dedicated gps units. When the other guys found out halfway through the ride that the route had more points than their gps would load, I was the only one left with the route. I had preloaded the maps for the area, so even though we had no cell coverage I had maps and the full course to lead everyone out of the woods the last sixty miles. Loads multiple routes, caches large areas of maps for use outside of cell coverage, lots of route info, supports gpx and kml and importing and exporting from emailed files to make sharing easy.
