I've been looking for a while and even looked at television broadcasts. First the good: The unit is quiet, has a decent display, many programs to choose from and looks good. The assembly was feasible. Trying someone from the manufacturer in Germany to reach by phone repeatedly failed, because one ring after 8 minutes, is simply thrown out of the line (after 10 attempts, I switched on the email) Apart from a recorded message for more than a week no response. I had incautiously not immediately set the correct time at the beginning and afterwards it is virtually impossible. Also a reset of the computer does not seem to be working. The display of temperature and time is always a joke, because the display is dark and both numbers are only be guessed at close range because they are only slightly brighter. This is not really tragic, but at the price it should not be. Much more annoying is the catastrophic pulse measurement: With your hands on the handlebar remains stable between 80 and 100, a direct dependency on the difficulty of driving can only be guessed. At the same time I allowed myself to Christopeit pulse belt. Practically at the same time, since only one pulse measurement is (handle or chest belt), both values differ by set at 60 to 90 °. The truth lies somewhere in the middle, because my Forerunner works very reliably, lies with its values in the middle, which is also my personal experience etspricht. In order for the programs to operate pulse depend are overwhelmed and totally free. This time, I believe, with a Kettler would not have happened.
