STAY AWAY
me too and i bought it from wristech, the thing
looks good and small enough but the readings!!!
well, i did not buy this as an accessory or as a watch, I should have paid a little more, and but something that is actually able to measure blood pressure. this thing seems to be just picking a guess and it is usually wayyy wrong (my sister is a doctor). i think it should be banned because they are just playing with human lives.
final word: STAY AWAY
