I have a Fitbit HR. I've heard from some of my friends that their model (not the HR) is great and they have no problems with it, but I have repeatedly had sync issues with mine. I'd go a couple of days unable to sync to ANY device, and then the techno gods would wave their magic wands and all would be well with the world again. At one point, I went a week without being able to sync, and that's when I called customer support. They walked me through all the help steps which I'd already done ad nauseum via their online guidance, and they finally decided that yep, my wristband just wasn't working. So they sent me a new one. Okay. That made me feel better.
Until I got the new wristband.
How much do I really want to know how many steps I walk each day? It was handy for recording exercise sessions and syncing those with my food app, but in the grand scheme of things, I've declared this tool a POS. It's often awkward to wear, and for something that works, at best, sporadically, I'm done. Maybe one of the other models would be a better option, but I've done my part in jumping on the fad bandwagon.
Do you have a Fitbit? (or other motion inducing/measuring device?)
