I was a doubter until I went on a trip to Colorado with my daughter who uses a Magellan. On the Interstate it was not of much use except as a diversion but once we reached Boulder, it was wonderful. We found my granddaughter's apartment with no problems; the U-haul dealer, a vegan restaurant, the Celestial Seasonings plant, a University of Colorado dorm building, etc. without fail. I calculate that I will recoup the cost of the Rosdmate that I purchased in short order just due to the savings in gas not having to go around in circles trying to navigate in a strange town.
