Customer Ratings & Reviews

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.

This item is very limited in supply and a great way to track your health habits using the Nike watch!

It is a good tracker, and it fits perfectly at my shoes. So far, i didn't find any problems yet. The device is all good all in all.

Excellent product by nike and apple, very useful at a reasonable price

This product was purchased as a replacement and it served its purpose well.

Nike+ sensor for their shoes which can be tracked on your IPhone using the app. Works great and can be calibrated through the app.

I'm 36 and have just begun getting into running. I play other sports but have never been excited to run. With this interactive product it allows me to see what I've done and it tells me where I've improved and where I've slacked. The voice overs from professional athletes are motivational.

I run on a treadmill and this device will track my progress as I continue to run indoors.

This product is outstanding when it works, however linking the sensor is a huge pain. The first time I tried to link it, it took a very long time and I retried linking it several times, it took a couple of days before I could finally get it to link. Then, the first time I used it, it worked really well, until the link to my sensor was lost, and I have not been able to regain the linkage. I am very unhappy with this product and the difficulties linking it.

It is small enough to use in any shoe and it tracks all of my steps easily.

nike used to have these in shoes but now you dont even need it

Definitely makes me excited to go work out! Love how interactive it is and how you can track your exercise!

Good sport stuff nice to handle Looks perfect and cool
