The TomTom Runner I have now for about 2 months while jogging (now since 192 KM) in use and I am always happy about purchasing this Running Watch. The clock connects with me in a few seconds with the GPS. The display is easy to read on the large display and can be adjusted individually. I have the Running Watch adjusted so that I get the distance traveled displayed during the run size in the middle. Time and average speed, I see in the top left and right. Left and right keys you can the other measurements can also view selbverständlich such as pace, heart rate, stopwatch, etc .. The operation via a button is also a good solution. It works much like a Loystick. The different functions and settings can by pressure (up, down, right, left) are selected. The chest belt also works properly and can be felt when running hardly. After the race the clock to load via USB to the PC and is available with the associated software via which one can save his runs on the TomTom website. Here you can look at all the data again, can be evaluated, the distance traveled display graphically and compared with the previous runs. The Customer I am also very satisfied. I contacted this because I damaged the clock for about 3 weeks in a fall (glass kaput) had. The friendly staff has sent me a new account for 85 EUR, which also arrived a few days later. I highly recommend buying this clock.
