This is a nice little device. Does what it's supposed to and is very compact. In many ways, it's vastly superior to other super small ECGs like the AliveCor. It lacks some of the features of the larger models, such as B. the possibility to set an interval of more than 30 seconds or the possibility to connect electrodes. But it's small enough to fit in a shirt pocket and weighs very little. However, less than three months later, it failed completely. One day it worked, the next day it didn't. I've checked and made sure it's fully charged, but it still doesn't work. The battery indicator still works and shows the charging process. Nothing happens when you press the button, which is both a switch and a toggle switch, to start reading. I have previously purchased Contec branded products and they have been reliable. This is the first pipe.
