Measuring
Type
Type	Wrist	Wrist
Irregular heartbeat detection
Irregular heartbeat detection	Yes	Yes
AFib detection or ECG
AFib detection or ECG	No	No
Method
Method	Automatic oscillometric wrist measurement during deflation. Exact UK item 65046, EAN 4211125650469; SK2 voice-language version. First-sale date unconfirmed	Automatic oscillometric wrist measurement during inflation, explicitly described in current exact manual despite Gentle+ marketing name. First on-sale date unresolved
Accuracy
Accuracy	Exact manual display accuracy ±3 mmHg for systolic and diastolic pressure and ±5% for pulse. Systolic range 60–260 mmHg, diastolic 40–199 mmHg and pulse 40–180 beats/minute; cuff-pressure range 0–300 mmHg is separate	Static pressure accuracy ±3 mmHg, pulse ±5% of readout; systolic 60–255 mmHg and diastolic 40–200 mmHg. Current manual pulse range 40–199 takes precedence over website 40–200; cuff-pressure display range 0–299 mmHg is separate
Clinical validation
Clinical validation	Exact manual gives an unspecified clinical-test maximum permissible standard deviation of 8 mmHg, without identifying a published study. Medaval reports no peer-reviewed clinical validation information for BC 21, but incorrectly labels its measurement site upper arm; exact maker manual establishes wrist measurement. Independently established headline validation omitted	Manufacturer website claims BIHS A/A and manual states ESH testing; Medaval exact-model record reports no peer-reviewed clinical validation evidence. Headline validation omitted rather than treating manufacturer claim as an independently established trial
Features
Features	Spoken instructions and results in German, English, French, Italian or Turkish for UK item 65046; three volume levels or off. Shared data sheet separately lists item 65040 with English, Spanish, Polish, Arabic and Farsi; those languages are not part of this UK version. Irregular-heartbeat warning, coloured classification scale, date/time, application-error messages and automatic switch-off. No dedicated AFib screening, ECG, movement detection, heart-level position or resting indicator	LED positioning indicator helps set wrist at heart level; inflation starts after 5–8 seconds. Ordinary irregular-heartbeat indication, traffic-light scale, cuff-fit and arm-movement indicators, low-battery warning and automatic switch-off after approximately one minute. No dedicated AFib algorithm or MAM sequence established
Cuff
Cuff fits
Cuff fits	14–19.5 cm	13.5–21.5 cm
Cuff
Cuff	Attached wrist cuff for 14–19.5 cm circumference. User must position the cuff at heart level; no electronic position guidance	Attached wrist cuff fits 13.5–21.5 cm according to current manual; clean marks with damp cloth and mild detergent

Readings stored
Readings stored	60 per user	60
Bluetooth and app
Bluetooth and app	No	No
Memory
Memory	Two users with 60 dated readings each; oldest overwritten when full. Average of all stored values and morning (05:00–09:00) or evening (18:00–20:00) readings over the latest seven days. Deletion clears the selected user's entire memory	Stores 60 readings with date/time, oldest overwritten when full; readings retained on battery replacement while clock resets. New result can be excluded; saved history clears as a whole rather than individually. Manual says per user but exact labelled controls/display establish no separate user selection, so no headline user count
App
App	No Bluetooth or connection from the monitor. Current Scan & Save support captures displayed values using a smartphone camera into beurer HealthManager Pro; not automatic transfer	–
Power
Power	Two 1.5 V LR03 AAA alkaline batteries; approximately 200 measurements depending on blood pressure and inflation pressure. Battery operation only	Two 1.5 V AAA alkaline batteries, approximately 320 measurements with new cells. Current support table incorrectly lists four AAA cells; product page and exact manual both specify two. NiMH rechargeable cells supported but charged externally, not inside the monitor
Design
Display details
Display details	Non-illuminated LCD with black digits, maker size 3.8 × 4.5 cm. Physical membrane memory and start/stop controls; low-battery indicator. Manual IP22	LCD with ON/OFF, memory and time controls; LED positioning indicator. IP22 in current exact manual
Size
Size	Exact manual and September 2021 data sheet give 87 × 67 × 31 mm (L × W × H) and approximately 105 g without batteries; data sheet specifies cuff included. Current product table instead gives 87 × 67 × 70 mm and 187 g excluding packaging, with weighing conditions unspecified; differences unresolved	73 × 66 × 38 mm; 124 g including batteries
In the box
In the box	Monitor with attached cuff, two AAA batteries, storage box and instructions. Current product page also lists a blood pressure record	Monitor, storage box, two AAA alkaline batteries and blood-pressure diary listed by European manufacturer; official instructions available
