Device is easy to use. Unfortunately, the systolic values by about 30 mmHg appear too high. The diastoliche value is only slightly and therefore more acceptable in the deviation with 5 mmHg. The pulse appears relatively accurate. Has been tested with more than one person and compare devices. It is strange when compared show all devices (3 pcs) the same values with only 2-3 mmHg difference and Bosco is just higher by an average of 30 mmHg. Whoever, therefore, has to rely on accurate values should leave it alone. Maybe I just caught a runaway ?? The 1 Star is only for the usual fast delivery.
