Is polar HRM 810i worth it considering its high price? Sigma sports will be releasing its new HRM PC 15 this june. I need your opinions to compare sigma HRM to polar whethere which one is better? I already read the reviews on mtbr. I need your latest opinions.

I like the polar HRM 810i because it is fully loaded with many features: calorie counter, pc connection, regular watch features, ECG, max / min / average heart rate. fitness test, relaxation rate, recovery measurement etc....
