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 65904, EAN 4211125659042. Current page heading and download labels identify BC 27 despite BC 28 in its SEO title and range tile; linked manual identifies type BC 27, technical model BC 28. 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	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 states a maximum permissible clinical-test standard deviation of 8 mmHg, but does not identify a published validation study. Medaval reports no peer-reviewed clinical validation information for BC 27; consumer laboratory tests do not establish clinical validation. 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	Irregular-heartbeat warning, coloured classification scale, date/time, application-error messages and automatic switch-off after approximately one minute. No dedicated AFib screening, ECG, movement detection, heart-level position indicator, resting indicator or voice output	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	Fixed wrist cuff for 14–19.5 cm circumference; exact manual requires the supplied attached cuff. Heart-level positioning is a user instruction, not an electronic position sensor	Attached wrist cuff fits 13.5–21.5 cm according to current manual; clean marks with damp cloth and mild detergent
Connections and memory
Users
Users	2	–
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 readings and seven-day morning (05:00–09:00) or evening (18:00–20:00) averages. Selected user memory can be cleared	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. Scan & Save captures the displayed values using a phone camera into beurer HealthManager Pro; not automatic wireless transfer	–
Power
Power	Two 1.5 V LR03 AAA batteries. Exact linked manual claims approximately 170 measurements depending on blood pressure and inflation pressure; current product table says approximately 300. No mains operation established	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	LCD with black digits; current maker table gives 3.5 × 4.0 cm and claims illumination, while FAZ Kaufkompass's exact tested BC 27 has an unlit display. Illumination remains unresolved rather than assuming a hardware revision. Physical start/stop and memory 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 linked manual 84 × 60 × 29 mm (L × W × H), approximately 92 g with cuff without batteries. Current web/data sheet instead gives 60 × 84 × 55 mm and approximately 171 g excluding packaging, without equivalent weighing conditions; conflict 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 and data sheet also list a blood pressure record	Monitor, storage box, two AAA alkaline batteries and blood-pressure diary listed by European manufacturer; official instructions available
