Fairly good, needs a little work

I agree with the others - it seems pretty accurate regarding step count and distance. I have tried it at the health club to compare it to the distance on our walking/running track, and it is pretty good. However, I am also frustrated that it wont work in the background, stops if you access your iPod or answer a phone call, and stops sometimes for no reason that I can determine. I must bump the display somehow. I have also found that it does not work well when held in your hand. Clipped to a belt or in a pocket work fine for me, but held in my hand it undercounts by about 40%.
