The chest strap can be easily and quickly create, does not bother and will be recognized relatively quickly from the clock also. Pulse and calories burned agree to my feelings, but the fat consumption I doubt (which personally does not bother me). Also setting the clock went really quick and easy thanks to the good guidance.
For water resistance: Had the clock once so far in the shower off her but has probably not mind :) continues to function properly. Accordingly, a cleaning under running water is no problem even when the chest strap is not. The pocket for I find a nice plus, as always stays together everything and nothing is lost.
All in all, a strong buy recommendation, even (or erstrecht) for heart rate monitor newbies :) Enjoy!
