Method
Method	Automatic oscillometric wrist measurement during deflation. Exact white UK item 65044, EAN 4211125650445; BC 27 dark-grey item 65904 has a separate maker product record. First-sale date unconfirmed	Automatic oscillometric wrist measurement during inflation, marketed as IMT/Comfort+; exact 2015 and August 2020 operating instructions both explicitly describe inflation measurement. 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 and pulse ±5% of readout. August 2020 manual gives 20–280 mmHg blood pressure and 40–200 bpm; current support instead lists separate systolic 60–255 and diastolic 40–200 mmHg ranges. Cuff-pressure display 0–299 mmHg is separate
Clinical validation
Clinical validation	Manual gives an unspecified clinical-test maximum permissible standard deviation of 8 mmHg for systolic and diastolic pressure, without identifying a published study. Medaval reports no peer-reviewed clinical validation information for BC 28; headline independently established validation omitted	Exact W2 Slim passed adult ESH-IP 2010 and ANSI/AAMI/ISO 81060-2:2013 protocols in Bing et al., published 2016; STRIDE BP lists a validated 13.5–23 cm cuff. This is exact-model evidence, distinct from later W3 Comfort equivalence. Study date does not establish first retail sale
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	Ordinary pulse-arrhythmia indication, cuff-fit check, arm-movement warning, colour classification scale, low-battery warning and automatic switch-off after approximately one minute. No dedicated AFib screening or MAM sequence established
Cuff

Cuff fits	14–19.5 cm	13.5–23 cm
Cuff
Cuff	Attached wrist cuff for 14–19.5 cm circumference. User must position the cuff at heart level; no electronic position guidance	Wrist circumference 13.5–23 cm; damp cloth and mild detergent for cleaning

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	Up to 60 dated readings for each of two users selected by physical user switch. Oldest overwritten when full. Memory retained on cell replacement while clock resets. New reading can be excluded; stored history clears together for selected user. Instructions describe individual recall, not an automatic all-readings average
App
App	No Bluetooth or connection from the monitor. Current Scan & Save support captures the displayed values using a smartphone camera into beurer HealthManager Pro; not automatic transfer	–
Power
Power	Two 1.5 V LR03 AAA alkaline batteries; exact manuals claim approximately 170 measurements depending on blood pressure and inflation pressure, while the current product table says approximately 300. Battery operation only	Two 1.5 V AAA alkaline batteries, approximately 320 measurements with new cells. NiMH rechargeable cells supported but charged externally. STRIDE's additional-feature table mentions AC adapter and PC link, but exact operating instructions establish neither interface; those claims are not adopted

Display details
Display details	Non-illuminated LCD with black digits, maker size 3.5 × 4.0 cm. Physical start/stop and memory controls; low-battery indicator. Manual IP22	LCD with ON/OFF, memory and time controls, user switch and colour classification scale; IP20 in August 2020 manual
Size
Size	Exact English and March 2022 multilingual manuals and January 2019 data sheet give 84 × 60 × 29 mm (L × W × H), approximately 92 g with cuff without batteries. Current product table instead gives 60 × 84 × 55 mm and 171 g excluding packaging, with weighing conditions unspecified; differences unresolved	81 × 65 × 21 mm; 115 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. Dedicated English manual's footer is September 2019 despite its download filename using March 2022; newer multilingual manual has the same core specifications	Monitor, storage box, two AAA alkaline batteries and blood-pressure diary listed by surviving manufacturer page. Product resource is Arabic regional maker page; support and linked instructions include English
