The clock is beautiful, light and strong. The chest strap keeps even at a fast pace and is conveniently located. Operation is easy and self-explanatory. I could also link quickly with my phone the clock. Only the PC program is not working. The installation is not yet possible; I made the mistake not been found. But is probably caused by PC and therefore does not suit for the clock. In short: ideal clock for all who want to monitor their training and thereby improve. Can only recommend it.
