It doesn't work well, it has marked my arm with all the pressure it takes and then gives an error.
I will return it.

Works fantastic but i'm not sure correct reading by minus 4% less serena 120 and now we're reading second test 116 🤔 🤔

It works well, although it seems like a toy. The result of the pressure measurement is correct. It is compact, with a short hose. It operates with batteries or a type C cable but it is not included. Could include a small cable. The use is not so intuitive but, reading the manual it becomes clear.

Delivery is fast. The packaging is intact and not wrinkled. The blood pressure monitor is working. Thank you.
