All day monitoring of heart rate and blood pressure – Bluetooth fashion smartwatch (Only For Reference, Cannot Replace Actual Medical Test Kits)

The size is also appropriate and good for the price. It would be better if the same seller sold the wrist and protective film together.
The delivery took two weeks. I came sooner than I thought.

I’ll try and add more.
The size of the liquid crystal is about the size of a combined four female adult thumb nails.
