Overall Good
Overall a good item. With nothing to compare it to, as I was using the Timex GPS. I love the fact theres no pod for the GPS. The watch itself is a bit big, but I have gotten used to it. I just wish it could be used for swimming.
Great training tool
This is the best training tool I've ever bought. It tracks all the data I could want and is easy to upload to a computer as a training log. It can be used for biking and running, even back to back with brick training, and you will have all the info from each workout saved.
Since it's GPS, you can even view where you went on a map, making it fun to share with friends where that last long run took you. I haven't used the provided training software, but use the device with www.motionbased.com, which is a great companion to it.

Garm Forerunner 301
All in all I really like it. It is useful to see total distance traveled and heartrate and calories burned. I have come to really appreciate it and I feel lost when I run or bike without it. From what I understand the Garmin 305 (new version) has some of the kinks worked out - it picks up the satellites faster and has four readouts on the screen.
