I received an offer flash. For the price, nothing to say. The device transmits a feeling of solidity and precision of measurement. However it should offer the option to make 3 steps away and make way for the average still increase accuracy. Moreover, the link program Bi Omron is not compatible with the Mac system IOS what I consider a serious shortcoming. I was even tempted to give only 3 stars because of it. Their page indicates several months it will be soon. We will definitely not have the same notion of "soon" ... Attention Apple users !!!!
