I used to date a blood pressure display without the need to connect an iPad to use it. Suffice to say that this is not practical and the camera finds herself in the closet. This new blood pressure, autonomous, is much more convenient and much easier to use. Simply position the monitor on her wrist, lower or raise the wrist as shown to position the device at the right level and automatically start the measurement. An icon indicates whether the bracelet is well placed. The values measured in mmHg, are almost identical to that of my other monitor. It saves up to 90 measurements and averages should last 3 measurements on the last 10 minutes. I regret that it does not support multiple users as these averages are useless if used to several people. Some buttons and more would also have been preferable to avoid resorting to the doc, fortunately very accurate. Small detail, the housing cover is too heavy, vacuum, it is impossible to leave it open without falling. The photo is faithful and the device and the quality is excellent. If, like me, simply being in the presence of a "white coat" for the voltage, you will surely be reassured with this device.
