FitVII H56 notendahandbók

Measuring accurately on SpO2. gt5 is a very cost-effective watch.

I like this GT5 watch because it looks like Apple and can dynamically monitor blood oxygen, blood pressure, etc.

GT5's blood pressure, blood oxygen and heart rate are more accurate. It only costs you ten dollars more.

I found this watch on the Medical News Today website. When I found it was $40 cheaper than the GT5 here, I immediately bought it. The US delivery was very fast. I received it in a few days. As it described, the blood pressure is more accurate. But the blood pressure needs to be turned on in the APP, which is a bit troublesome for me, and the customer service immediately helped me solve this problem.

I bought the H56 blood pressure watch because I saw many websites recommending it.
The H56 is a solid watch overall, but its blood pressure detection isn't as trustworthy as the GT5. The GT5's readings were always spot-on, but with the H56, I've had inaccurate measurements, which is quite frustrating. I have to suspect that the recommended merchants received Amazon commissions for the recommendations.
