The Forerunner 645 Music has performed well for as what Garmin promises, straps are easy to change, Battery lasts one week while using it with the heart sensor 3 runs during the week of one hour and listening to music

The main problem I have is that the music cuts out mid run (it's not a bluetooth problem).

I had the Adidas Smartrun for 3 years until they dropped support (short battery life, music on phone, good running stats, wristHR, no smartwatch functions

Music without any sort of wires is perfect

I noticed that the music skipped, like an old CD player

So...useless music feature.

The sole purpose of making the purchase was to enjoy music on my long runs, but with such a poor connection , it somewhat defeats the point

Their accuracy, their ability to get a satellite signal quickly and their features are second to no other brand.----------------------------------------------------------------------Garmin 645 Music: Recommended

the other features are great (wrist heart rate monitoring, music, smart notifications (with ability to respond with pre-selected answers) and so much more.

So in summary, watch is amazing but the music is a gimmick and not really useful

BUT, the music part and the FRUSTRATION that it causes because it JUST DOES NOT WORK discounts all the good that Garmin does with the rest of the watch.

For the first couple of weeks I had the watch, I ran without music and liked the in-run information I was getting

3.The music is the best nice to have, I have a big

I'll hold out and see if Garmin makes a music capable watch with touchscreen next year.

This is not the case, essentially the Garmin 645 Music is a mp3 player from the early 2000s, like the original IPods

I would have been very frustrated if I were out for a hard run, as it made me stop wait for green triangle screen to clear, restart music and make sure my run was still being tracked

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