I own one of these and while the price is a great deal almost 1/2 of MSRP, the watch needs lots of updating in terms of the GPS functioning part of it.

I will go on a run with one hill in it and when i get back i am told that I had a net vertical climb of 1300 ft and still managed an 8:45 sec mile throughout the run.

Trust me, i cannot keep that pace at that climb.

I would have waited for a better one to come out now that I have used this one. Or at least let them come out with another model with all the kinks worked out.
