Query: Not what I expected

I was so excited to use this watch since it was recommended by a runner friend of mine. But this watch seems having difficulty to locate satellites and it takes much longer time than expected getting connected. I wore it for my half-marathon race in NYC in January 2008, the pace was not accurately recorded, and after losing satellite signals in the middle of race, the data stopped being recorded. Now I stopped wearing this watch.
