We acquired this monitor for an elderly person in need of monitoring on request of the treating physician. We opted for the OMRON M10-IT is at an attractive price on the amazon website (65 euros against 100 euros more on medical sites!) You should know that the device is precise, solid and quick in making the measurement. It has an internal memory of more than 80 measures. It can manage two different people and make measurements for those "guests" who do not come to memorize and "parasites" and not the actions of two people locked. This device is approved by lAFSSAPS (French Agency for Safety of Health Products). The software is easily installed, but sometimes you have to wait in front of windows where nothing seems to happen (during the initial installation). Then the software is itself fairly intuitive. Important note, contrary to what is announced in the technical specifications, the software can be installed in French. Do not physically connect the device to the USB port as long as you have not installed the software. To import data, you must first create at least one user. Then he must still navigate the software to finally find the Import tab (click on the "Display graphic" and then in the new window, click on the "download data"). Then, the graphics are alone. The export pdf exports only the measures and not the graphics, that's a shame. However, you can print your data and take them to your doctor, or send them by email in pdf format if you are not too fussed about medical confidentiality (files sent by email will be sent "in the clear" on the Internet This means that your internet uap provider can access at any time your email archives, etc.) ... The monitor does not hurt in the arm but it is true that this strong greenhouse when the cuff is "pumped". Note that the device is made in China, but the sensor would be mounted in Japan, according to the information given in the instructions ... That's all we can say at the moment, we may be adding notes to this comment in the future if it was appropriate to bring new interesting features.
