The operation is fairly intuitive and well thought out by the navigation knob. The GPS reception is good, but takes in not available "QuickGPS" pretty long to connect. Is Quick to GPS, it takes less than 10 seconds not.
The PC software works for me without problems. In addition, without ceremony after each sync a .gpx file which then z. B. are automatically generated can be imported with runtastic. The process takes a minute.
Unfortunately, there is for the clock only three stars because a very important function not working properly. The Pace is just extremely reproduced time is delayed. At a speed change about 1km, it takes up the clock again the correct speed (min / km) indicate. I hope this will be fixed in a software update. Then I would correct the rating 5 stars.
Conclusion: For whom the Pace is important but perhaps watching a different clock. For all others, it is a great Running Watch

Update 30/08/2014
After the update the clock on the version 1.8.5 the Pace runs much faster and stabilder. Tempo changes are well recognized and in the meantime also reproduced relatively accurately. Here Tomtom has well improved. Therefore, I can lift on the 5 Star rating now.
