Have bought the device after a long search as a sort of reference device. The measurements are for the first 5-throughs relatively equal in the result, and surprisingly lower than expected (compared to the measurements at the doctor). See the instructions and the device as an upper limit to 135 systolic, so that in this respect fit on my results, but would 135 perceived as normal at the doctor. Anyway, the measurement results make a meaningful impression, and that was important to me. I bought the IT execution to a long-term view to have to be able to see a curve. Login to the portal, etc is OK and easy. But the transmission of data or management has it all. There are 2 users on the device. Now I have accidentally uploaded the data of the second user, and this land then just for me (first user). Then the second user has precisely measured as "User 1". To no false data upload again, I deleted all the measurements of the user 1, and then himself again carried out a measurement. No way, the data from the second user were also just uploaded and now make a beautiful senseless curve for me. No way to delete the data on the portal. Only you can add manually. The operation is not exactly ideal, for example, that the time was for whatever reason set until I noticed the that the period was limited ("where are my most recent data ...?), Then OK. Why is this so at the start of portal set? Lauter mousetraps. Also that the device must be switched on yet, until you press the button to upload the software. Otherwise works uploading not automatically, but the unit does not activate itself again, but you have to turn on and press again uploading. Again mousetrap. I imagine only ordinary people who do not want to play around technically. This should be solved differently. In AppStore at Apple, there are already an app, but the devices are still not on the market. For the United States has these days (at Amazon USA it was from 30.09.14 available but could not be sent to us for restrictions, probably by the manufacturer) a BP786 available, which would be technically the M500IT same but now with Bluetooth and app works that I would have wanted, but no reliable and accurate instrument, not even from other manufacturers, I have otherwise found on the market. This will probably be soon, probably, also introduced us to the other naming.
