I've noticed just after 1week usin' 945 that there're some probs to solve regardin' in 1st HR wrist, 'cause in a cardio session and sitting on a bench the device shows me 183bpm range and tha other great prob is the Physio TrueUp used to tranfer some data from pervious deveices...doesn't work properly...I've been cancel all datas and start from zero with the new device to have some lost data….
Ths test starts now...
