Customer Review

Unwrapped, charged and made a trial measurement. Help, what values? Repeated measurements showed values ​​that were up to 20 mmHg higher than those of the comparison device. Also differs each measurement in strongly from the previous off. My guess is, it's up to the very ill-fitting collar. Even if you have no upper arm muscles, it would probably still down too far. Aside from making the USB interface also problems. The device does not recognize the PC, but the PC the device. This problem I am now not pursued because it is not useful for accurate measurements anyway. The device will go back again.
