The first choice is where the cuff goes: Medisana's BU 582 and BU 584 measure from the upper arm, while Rossmax's S150 is worn on the wrist and travels more easily. The second difference is how results are stored – the Medisana models carrying the Connect name pass measurements to a phone, while on the others the readings stay in the device's own memory. Measure your own arm against the cuff's circumference range, because a cuff of the wrong size distorts the reading.
