It's funny how history keeps repeating itself. Last month, the Hammer of Dawn was unresponsive and I ordered a new watch only to find the next day the watch came back to life. I was able to cancel my order and everything was good.
But now, a week before the marathon, the watch died again. So I ordered another Garmin Forerunner 405. This time it's $40 cheaper!
Anyway, I think I'll like the new device.
