Personally I dont have one....I used to and found it only counted like every 6 or so steps
so it was really innacurate....I know a lot of ppl use them and they are great though
(must just be cos Im a stingy person who got hers free with a tub of margerine from coles
haha) I think experts say that for good health we should be aiming for 10, 000 steps per day, and any extra is a real bonus
Im sure someone else will know for sure though!
