What reviewers say

ETM and PC-WELT liked the easy-to-fit cuff, clear display and straightforward Bluetooth transfer. ETM found measurements quick and the cuff comfortable, but criticised the lack of guest mode and individual-reading deletion. PC-WELT reported reliable operation after years of daily use, while noting frequent battery changes, an unusual measuring sound and no protective case. Their accuracy checks were practical tests rather than independent clinical validation studies.

Measuring

Type: Upper arm
Irregular heartbeat detection: Yes
AFib detection or ECG: No
Method: Automatic oscillometric upper-arm measurement during inflation; exact BM 81 easyLock item 65511. First on-sale date unconfirmed
Accuracy: Maker display accuracy ±3 mmHg for systolic and diastolic pressure and ±5% for pulse; systolic range 50–250 mmHg, diastolic 30–200 mmHg and pulse 40–180 beats/minute. Cuff-pressure range 0–300 mmHg is not the systolic measuring range
Clinical validation: Maker claims clinical validation and ESH recognition; Medaval's April 2025 list places this model among monitors with internal or unpublished validation. Independent published exact-device validation not established; headline validation flag omitted
Features: Cuff-fit check, irregular-heartbeat warning, coloured LED risk indicator, date/time and automatic switch-off. No ECG or haemodynamic resting indicator; not a continuous ambulatory monitor

Cuff

Cuff fits: 24–40 cm
Cuff: Integrated easyLock upper-arm cuff with press-and-turn adjustment for 24–40 cm circumference; no separate tube or hook-and-loop fastener

Connections and memory

Users: 2
Readings stored: 120 per user
Bluetooth and app: Yes
Memory: Two users with 120 dated readings each; oldest overwritten when full. Averages of all saved readings and morning/evening readings from the latest seven days. All readings saved to a user memory; deletion clears that user's entire memory, without individual-reading deletion or guest mode
App: Bluetooth Low Energy transfer to beurer HealthManager Pro; can be used without the app. Current instructions specify compatibility with Bluetooth 4.0 smartphones/tablets, not an exact radio-generation claim
Power: Four 1.5 V AAA LR03 batteries included; approximately 300 measurements depending on blood pressure and inflation pressure. Battery replacement retains readings but requires resetting date/time. ETM's AA battery table conflicts with the exact maker manual and PC-WELT's AAA description
