So start with the superficial: a very nice product, very Apple in its design. Positives: * Quality printing: the cuff is thick and comfortable, leather look outside, lined inside for not cold on the skin. * Installation very simple: when you use it for the first time on the iPhone (I said I have an iPhone 4), automatically, a window tells me that I do not have the necessary application and wondering if I want to download. By clicking yes, it automatically connects me to the AppStore and offers me two applications. We must choose the one whose logo is blue (also reproduced logo in the manual supplied with the unit). * When starting the application, a user guide of the pressure measurement is displayed to allow us to position the device on the arm and we moved into the proper position. * The application itself: if we create a Withings account, you can register its actions (creating different users, you can even sort the measurements), you can even email them to her doctor. (However, I have not tested this function because I do not have the address of my physician!) * The displayed voltage corresponds to my usual tension, and by measuring it several times, I got mensures never equal but always equivalent. So the camera seems to me reliable.
Disadvantages: * Arm diameter should be between 22 and 44 cm, so not possible for people too thin * You really sitting as described in the manual, otherwise the measure fails. This to me is all the same happened three times in 7 or 8 bars.
Finally, I think that this camera really worth its price, provided however, often need to check its tension!
