Sigma onyx balance - HRM
Specs, here: http://www.sigmasport.com/en/produkte/pulscomputer/onyx/onyx_balance/?flash=1 Is it recommendable? I really need to get a CHEAP, but GOOD HRM. My price maximum is 88 dollars (500 Danish Kroner) It basically just needs to a) Function. b) Count calories. If this really sucks, is there anything else you can…
