Nike+ - Sports Kit for Apple® iPod™ nano

The Nike Chip fits comfortably under your sole and syncs directly to your smartphone for tracking of data. Does not track data however on a stationary bike or elliptical.

This is a great product because it seems to be very accurate of the steps I take. It also helps to keep me motivated to keep working out.

Been wanting one for a while to use while running. Definitely recommend for anyone who wants to use when running

Enjoy using with my app when running. I was lost when mine went out

I would give this product 5 stars across the board of it were not for the fact I somewhat question the accuracy of the distance it shows. It seems consistently a quarter ml to a full ml off from my phs gps based running log.

I bought it replace an old one. Was really happy to find it at best buy at a good price. Super happy with the ordering and delivering. works great

My wife uses these more than I do; I never remember to put them in my shoes; I usually just lace them up and go! She has gone through at least 3-4 of these in the last 4 years. I do not know if that is the 'life expectancy' of the product or not, and the cost is reasonable for the use she gets out of them. The data tracking is nice, and it does what it is deigned for; another key thing I always forget to do, but luckily I sync my music a lot so it resolves itself, lol.

I enjoy the product and use it 3x's a week. Haven't hooked it up to a computer yet, but I intend too. It was great for tracking my workouts and calories burned.
