Jawbone/Vivofit/FitBitFlex?

Does anyone have any of these fitness trackers? If so, are they worth it?

I keep seeing them on special offer at the moment - and am wondering if I would get enough use out of one.

I do run, so have a Garmin (not v good at picking up GPS though), and have Strava App on my phone which i use to monitor pace/distance.

This would be just for daily movement - as I am on a running break at the moment, and trying to lose weigh - so wondered if one would spur me on to move more?

Iwant, I use a vivosmart with a heart rate monitor but only for tracking indoor workouts, not as an activity tracker.
I find using the HRM is what really motivates me because it gives a good indication of training intensity and you can track improvements in fitness.
