Overall, I am satisfied with the counter, but it's a real gas plant on setting and use. There are too many options around this unit (ANT + cardio etc ...). I have not yet managed to put the GPS journeys made on the computer and the computer on the meter. The height difference, no problem. Just change winter time !! Otherwise it is very comprehensive in information level. In short, the user manual is almost an encyclopedia and complicated settings. So if someone wants to explain, he will be welcome !!
