"The concept is great but the sensor sucks!"1.0 starson by snorman59
Pros: The concept sounded great.....
Cons: stopped working after 5 minutes of use
Summary: Got new from Apple. I figure if you buy direct from Apple it should be a better product. I installed it in my shoe, went to calibrate, stepped on the treadmill and the unit quit working. No matter what I tried it did not send to my ipod touch. Will try to call Apple to see if they will replace.
