Verified Purchase(What's this?)
This review is from: Marware Sportsuit Sensor Case for Nike + iPod Sport Kit for iPod nano 3G (Black) (Electronics)
I bought this pouch because I don't like or use Nike shoes for running. I calibrated the sensor with the pouch on a treadmill and it was spot on. I use it on all my runs and it works like a charm and is always accurate. Anyone having problems with accuracy probably has the sensor upside or doesn't have the pouch strapped on tight enough.
Best $4 I ever spent.
