Excellent product. If it has to be GPS aided it has to be Garmin. Excellent accuracy. After initial few runs with GPS , the watch automatically syncs to your steps , heartbeat, and cadence and accurately gives readings when GPS not SW on. Remember the route has to be same , and frequency has to be same. Does have problem of flimsy strap and loop. Ensure you put scratch guard on it before use otherwise it takes on too many scratches.
