Impressions from the tonometer are very good, modern design, strong plastic, a handbag included (so as not to collect dust). The tonometer can work from usual finger-type batteries (4 pieces), and from the power supply unit. For 4 years of operation no complaints. The pressure is measured in the classical way: a cuff is attached above the elbow bend at a distance of 2-3 cm, a rubber tube is located under the cubital fossa, then we press the Start button. Next, we look at the result. There is a memory button. In general, a simple and reliable device!
