I tried a $129 blood pressure watch, and it came close to my Withings and Garmin trackers
Briefly

The YHE BP Doctor Fit smartwatch impresses with reliable blood pressure monitoring and excellent battery life, lasting over a week even with frequent usage. Packaged in a simple retail box, the only noticeable downside is its weak magnetic charging connector, which requires careful handling. The smartwatch features a stylish black aluminum body and a high-resolution display but presents challenges with the clasp positioning, causing awkwardness during use. Additionally, the inflatable cuff design limits customization of the band, yet the overall performance, especially compared to competitors, stands out favorably after thorough testing.
The watch's battery easily lasts over a week with regular blood pressure measurements, impressively maintaining performance despite its vibrant high-resolution display.
The overall construction of the YHE BP Doctor Fit smartwatch, while appealing in design, presents some usability challenges, particularly with the clasp's awkward position.
