I've got one of these Walk-O-Meters
I wore it yesterday on my waistband but it kept catching on the desk and if I sat too close to the edge of the desk, it pressed the button and reset itself so it didn't really work.
Thought I'd cracked it today and have put it on my sock. Have just realised that this means it's only measured half the steps I've actually taken! It reads 857 at the moment so I guess I've done 1714 steps? Eek, that's still a way off the recommended 10,000 - I'd better do some pacing before bed!
