OK, this is a reasonably priced smartwatch with a built-in accurate blood pressure cuff. I will give this product 5 stars. Everything is perfect, the blood pressure is very accurate, there are voice prompts on how to operate the blood pressure test, you can feel the "systolic" and "diastolic" like a traditional blood pressure monitor, very comfortable and accurate. In addition to blood pressure, there are the following functions that I am very satisfied with:
1. The sleep detection is very accurate, 100% recommended.
2. All vital signs of the watch are automatically monitored 24/7.
3. The weather forecast function has been added, which is very practical for me.
4. The alarm will sound when the body temperature is too low, and the heart rate is normal at present.
By the way, fitvii also gave me an X7 watch as a gift. This watch has many functions, but the blood pressure is not accurate. So I gave it to my niece, it may be more suitable for my niece.
