I've had a Nike fuel band for a couple of years now and its quite handy for getting a rough idea of what you've done, but I wouldn't rely on it. Its not accurate as it reads low on the steps when walking and also registers steps when I'm doing things like washing my hair, or moving my arms when driving the truck, but it does at least give me that jolt to move my arse.
Bought the wife a Jawbone for Xmas, just got the one that plugs into the phone as she only wanted a cheap one. Thats been really good, very accurate on the steps and alows you to see how you've slept. Downside is that its stopped working with my phone (HTC One M8) but I cant tell if its the band or the latest software update to the phone thats the issue. Customer Service is only open 10 - 5 Mon -Fri so I can't even ring them due to being at work
