Important: Before you buy, you should know that there is no clock on this software for the PC etc. The heart rate monitor via data collected are sent and analyzed by the Polar FlowSync web. Who does not want this information transfer, which should not buy this clock! I was surprised by the flow-line Privacy Policy (Flow is the Polar web service). Hui. It's worth it before buying read, I would say, because without this service, you can not take the clock quasi operating and do not evaluate its training data etc..
Otherwise: - Clock plus additional accessories looks very well made, the material feels good. - For my narrow arm (I woman) the clock is not designed. It is not possible for me, the clock must be created so that it sits halfway fit. That is due to the rigid band in the region which bears directly against the clock.
=> More I can not say the clock I have returned again ...
