very simple and very pleasant to use

Very easy to use. Just put it on the handful, the display inwards. The bracelet is not flexible as one might think. He already has a rigid curved shape like a bracelet. It is positioned even better on the wrist. Note that on the side you have drawings that remind you the right way to position the bracelet.

When you turn it on, you feel a pressure (as the doctor), a counter runs to finally give you the information.

The memory button to view the latest measures.

You have different results:

- High pressure Result
- Low pressure Result
- Pulse / minute
../ ..

As well as icons, a court case darythmie during the measurement, detection of irregular heartbeat ...

Blood pressure which, if I understand is a bar that moves up or climb to match the graph on the left side (from green to red)

The more complicated for the novice is to interpret the information. The doc says nothing. But I guess for regulars it does not pose any difficulties. I think a small page indicating what medium is acceptable, it will avoid unnecessary fears. So I search the net or I stand.

Note the excellent lighting, a backlit blue background with white writing very legible, beautiful.

I'm not able to tell you if the displayed data is correct, only a comparison with medical equipment could inform us ...

Finally, a device very simple and pleasant to use, very, compact design ... well, if data are reliable, it's pretty impressive for this price (29 to date)
