It eventually irritated my skin (I had burn marks right under the light) so I had to give it up. Even with regular cleaning, I could not stop the strap itching.

The nice thing about Garmin (the company) is that they gave me a full refund even though it was well past the 30-day return. I haven't gone back to do the research on avoiding the skin issues, but I hope some day I'll be able to buy a Garmin again.

This is one of those things where limiting the functionality of the device enhances the usability of it. I can easily do the 3 or 4 things I actually want a watch to do on my fitbit(stopwatch, heartrate, pedometer, see who's calling) and don't have to worry about dumb stuff like receiving phone calls or watching video on a tiny screen.
