Having heart rhythm problems, my cardiologist asked me to take the pulse regularly. Most of the time when I was in arrhythmia I was no longer my veins. By searching the internet, I came across the ring, and I was a little skeptical at first. Once the package delivered, I found a nice little ring easy to implement. The first tests remaining calm and taking the pulse manually, have confirmed the high accuracy of the heart rate. By moving the result is the same, in fact, a doctor Account for 1 minute impulses, the BS-CB001 is much faster, it extrapolates its measurement is performed in 10 seconds and he reports his custom Minute . The person who put his comment by testing on the treadmill was not to be regular in his training, which distorts the measurement. The other person rightly mentions the obligation to make good contact with the finger measurement is effected by a beam, this one is disturbed by external conditions.
That's a good little product that has nothing medical, but that can bring valuable help to control heart rate. Small detail I am not a seller of cardiobague, but I'm always curious of new technology, and I know recognize when a product is good.
