Query: Gets your heartbeat up alright

The watch is alright once it works - but today I waited 20 minutes before it was able to lock on to the satellites, and waiting for this thing time and again makes my heartbeat rise faster than in a full sprint.It's also a big, ugly chunky thing - not that I really care too much about that.Once it does finally work it's ok - measures various data such as distance, heartbeat and approximates calories burned. The attempt at measuring ascent/descent is ridiculous and all over the place. The Garmin Training Center software is a throwback to what made Windows 3.1 so exciting. The motionbased website is a tad better, and lets you compare your times with other runners, and is a bit more professional than Nike+ is for instance, but is still awkward to use.All in all it's a nice idea - sorry about the execution. Try again.
