I am very pleased with the running computer. The communication with the computer (with Apple) is working properly. The clock is quick to set up and evaluation of the data online self-explanatory. The clock is on the foot pod very carefully. I had during calibration (which is not necessarily required) on a 800m by 821m displayed route. A star I pull from for the low battery power the foot pod - the only truly annoying point. I run about 3 times a week per 1 hr. And after 4 weeks, the battery is empty. Since I have got a bit more expected, especially because the batteries (type 2032) are not exactly cheap.
