Any trainers equip their clients with wearable trackers (fitbit/jawbone up)? Would love to hear your experience!

I’ve had a few clients who did use the fitbit and they loved it. It was more for them (not for me although I found them useful as well) and to help them track mostly their daily caloric expenditure. For me it was interesting to see how many calories actually they burnt on each workout….(fun stuff)
:-).
