Product links

Type: Wrist
Clinically validated: Yes
Irregular heartbeat detection: Yes
AFib detection or ECG: No
Method: 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: 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: 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: 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 fits: 13.5–23 cm
Cuff: Wrist circumference 13.5–23 cm; damp cloth and mild detergent for cleaning

Users: 2
Readings stored: 60 per user
Bluetooth and app: No
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
Power: 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: LCD with ON/OFF, memory and time controls, user switch and colour classification scale; IP20 in August 2020 manual
Size: 81 × 65 × 21 mm; 115 g including batteries
In the box: 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
