I've been using mine for over a week now and have found that you need to move the strap up your arm when exercising for an accurate heart rate reading as stated in the instructions, once done the accuracy is comparable to my Polar H7 chest strap when exercising but is not giving me an accurate resting rate, I am around 48 bpm when sitting but this is showing me at around 60 bpm.
I have also read that it is not that accurate for high intensity workouts, not a problem for me as I train around 120-130 bpm max but something to be aware of. It also went mad on the flights of stairs reading the other day stating that I had climbed 45 instead of around 10, apparently the weather can affect this reading.
I am also finding the battery life is around 2-3 days instead of the claimed 5 which may make me return it. I do think it is a generally good product but still needs some refinement and cannot make my mind up wether to keep it or not. |
