Overall: I bought this watch off ebay. The fella who I bought it off said they are over rated and reverted back to a Polar. I just thought he did not know how to use the watch. Now I am in agreement with him. I have seen my runner club wear them then revert back to the older watches now. I never used mine in the end it was difficult to set up and the soft wear was rubbish. That said I have a Garmin 610 brill.
