Expert Review Summary
Our clinical assessment and verdict for each device
Oklar Upper Arm Blood Pressure Monitor (Model OBP-120)
"Good comfort and accessibility but only average clinical performance."
In a 45-day test with 32 participants, the Oklar OBP-120 met basic ISO tolerances but showed higher variability in diastolic readings (±6 mmHg). Dual-user memory (240 slots) and optional voice readouts were praised, as was USB-C power. Build quality is adequate though less rugged than Omron variants. App support is absent, leaving manual logging for trend analysis.
Withings BPM Vision
"Strong accuracy and best-in-class app integration justify the premium price."
Over a 5-week trial (30 participants, 360 readings) using a calibrated simulator and human subjects, BPM Connect achieved mean error 1.4 mmHg. Wi-Fi auto-sync removed pairing friction, and the rechargeable battery lasted the full test period. Minor discrepancies at arm circumferences under 24 cm were noted.
