Oklar OBP-120 Review: Feature-Rich but Middling Accuracy
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.
