Review title: Too hard to calibrate
Product review: We're having a devil of a time calibrating this device. I bought this for my partner, who doesn't fit well into Nike shoes, so he's continuing to use his favorite running shoes. He has the Marware sport suit for the sensor, which came highly recommended. Unfortunately, we haven't been able to get the calibration to work at all. Apparently, judging from all of the other messages from users, this is a known problem -- whether or not you're using the sport kit with a pair of Nike shoes.I think this is very much a beta product. Great idea, but just too buggy in its first version.
