and I love all the data it offers

The data that this device gives is unparalleled

Overall the device is good and provides accurate exercise data (which is to be expected from Garmin) .

Don't bother downloading any fancy data screens because to cram all the information on one screen requires making the fonts impossible to read while running.

Web interface is good and now two weeks in gets better because there is enough data for insight and the Firstbeat stuff to kick in

Another reason I chose this watch was the ability to use my chest Garmin HRM for more stable/accurate data, same one I use for cycling paired with an 820 computer, works almost flawlessly

Like the Pod it also began having issues displaying running dynamics data

If you want to write you own widgets/aps, the APIs and interface looks great and also the data is way more accessible than Fitbit

I've been wearing the Garmin Forerunner 645M for about a week now and love it
