What a great encourager. It's so discreet that no one knows you've got it with you. This little contraption is amazing. I love the fact that it keeps 7 days of memory in it PLUS resets itself at midnight. I've told all my friends & family about it. My only regret is that I had not found it sooner.Omron HJ-112 Digital Pocket Pedometer
