It is really easy to use and fits the need of every runner who owns an ipod. Easy to use UI makes it plug and play.
I bought a small pouch and attached it to a regular shoe.
I wish they made a battery pack.

I bought this piece to see how it works and now that I have seen it, I dont think I will buy it again once the battery dies.

I have 1st and 2second generation nano. The sport kit will not work with either. went to apple store and was told it will not work with any nano but the aluminum back nano, which cannot be bought any more.

Don't waste your money. The other reviews are just electronic store review salesmen.

Go to an apple store and ask the question. What apple product currently sold will the sport kit be compatible?

Answer!

None!

Okay, this is the most fun I've had with my nano, as well as the most motivating gadget I've bought for running. It's not expensive and yet really makes it fun for us running geeks who like gadgets or just like to keep good records of our walks or runs.

When you sync your iPod, your data goes to a Nike website that you can log into and create your own account. From there, it automatically uses your uploaded data to create a running (or walking) record. It's like a running log, only better. You have instant graphs of your totals (time and distance, daily-weekly-monthly, etc.), you can even set goals and earn virtual medals or trophies when you reach them, and you can invite friends and strangers to challenges, both individual and team. I've participated in several challenges and it's really neat to see others from all of the world get involved. It's a real running community.

But, best of all, even if you aren't interested in anything like that - if you don't want to track your mileage online - the sensor system motivates you. When I have a personal best for the mile, I might hear Lance Armstrong's voice congratulating me, or another famous athlete like Paula Radcliffe. Also, you can press the center button on your iPod at any time and get your current "stats" such as pace, time, distance, etc. It'll also count down or up your mileage as you run, letting you know that you only have a half mile to go, for instance.

Feeling tired and unmotivated? You can also select a Power Song - which you can hear at any time by with the press of a button. Very helpful for that last "push" at the end of a workout.

A great product. I love mine. Thanks Nike!

I have used the Sport Kit for over a year now. It's incredible. The instant feedback available about your running speed, distance, and time is great. After I calibrated it, which was very simple, I ran a 10 mile event. In the end, my iPod said I had ran 9.97 miles. So it's not perfect, but for the price you can't beat that.

The web site is great as well. My best friend lives over 1,000 miles away, but we can challenge each other to running contests (distance, pace, etc) and monitor it on-line. Great motivator to keep running.

The only downside, and it's not even enough for me to drop from a 5 star rating, is that the battery in the shoe sensor cannot be replaced, so you have to replace the whole thing. Mine lasted about 7 months.

I wear this on a pouch in my non-Nike shoe. I didn't need to calibrate it for my warm up walk and it measured distance/pace fine. However, after repeated attempts outside and on a treadmill it won't recognize my run mileage. I've tried to calibrate this thing at least 5 times and it stays at 0.0 for running. VERY FRUSTRATING!! However it still recognizes my walk rate. I don't understand what the problem and fix could be. If it would recognize my run distance/pace then this device would be great.
