Review on Blood pressure monitor AND UA-777 with standard cuff and mains adapter by Boyan Jakimov ᠌

I bought this device in a pharmacy. I have lifelong pressure at the level of the plinth. 90-50/80-40, sometimes even 50-30. This is the norm. I used to have a semi-automatic German device, everything was fine with it, I even measured through a sweater, no problems. But he stayed with his mother at home, when moving. And so I decided to buy a new one. I went to the pharmacy. There were only 3 manufacturers: China and 2 . They praised this device, they say N1, just pressed the button and you're done. However, already when trying to measure the pressure at home, I realized that with my pressure it is completely useless. I don't know exactly what's wrong. He measures the pressure of all his friends, but on my arm he does not find the upper limit and gives an error. Already as soon as they did not try to measure. On different hands, everything is according to the instructions, but no, a cuff error or just a mistake. I will sell it. Since I have never been able to use it for its intended purpose for myself since the moment of purchase. Hypatonics categorically do not advise him to take.
