I have this clock now since about half a year and the following can say! 1. The connection is always detected very quickly by chest strap and clock, I had in this area never had a problem and the values all have to agree as far. 2. The menu is in English, so it should each decide for himself whether his English skills are sufficient (annoying for me is there's plenty of heart rate monitors in German) 3. But now to my negative experience and that's the gray paint in normal everyday use (I wear the clock always) already provide some missing and the clock thus looks ugly! Zummengefasst means: great sports watch but just in this area because the paint is just down quickly! Sports Data can be transferred to PC (cable is)
