Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
One whitelisted source, SafeWise (Sep 2025), reviewed the Omron Platinum (the retail name for the BP5450 SKU) and named it the most accurate 2025 home blood pressure monitor, praising its clinical accuracy and unlimited app storage while flagging limited on-device memory. The verdict is editorial, based on reading user reviews plus a nurse advisor, not lab measurement, so no measured values are reported. (1 sourced review.)
Praised: Rated the most accurate home blood pressure monitor of 2025; Unlimited reading storage via the Omron mobile app; Clinically accurate with easy-to-understand results.
Flagged: Limited on-device memory (200 readings for two users) may hold only about a month of history for heavy daily users.
Thin coverage: only Wirecutter's fetchable text covers this exact model, and it is negative — in hands-on testing the iHealth Track "produced inconsistent readings in our tests," so it missed their picks. TechGearLab's page was unreachable during harvest, and Consumer Reports, Forbes Health, and MedGrade fall outside the genuine-tester whitelist. Treat this single-source verdict cautiously. (1 sourced review, 1 lab-tested.)
Flagged: Inconsistent readings in Wirecutter's hands-on testing kept it out of their recommended picks.
