The Checkme BP1S Blood Pressure Monitor is compact and portable and ideal for home use. The build quality is pretty good with the inline control unit and display being a metal construction with easy to read OLED display. This control unit can be recharged with USB-C cable (included). Because there is no separate large control unit like other blood pressure monitors, the BP1S is very portable to carry around. Optional is the AirBP app which can connect to the BP1S via Bluetooth and store your blood pressure readings. I would recommend this to keep a history of your readings as the control unit itself doesn't store this history.
