It is an excellent watch. There´s some details to improve, but it give you what it has. GPS is excellent in open sky, poor for indoor usage. Google feature is very useful. All the features works perfect, altimeter, barometer, temperature, compass, gps (location, average speed, vertical speed, tracking, etc).
It is not for rude sports, do not abuse from it, but anyway you have a high tech time piece in your hand and for your service and for a reasonable price. I highly recommend it for pilots and travelers.
