Guia do usuário HM18

Difficult to understand how to use. Not very intuitive

I purchased the HM57 watch for its cheap price, but the blood pressure monitoring doesn't match the accuracy of the GT5pro. The GT5pro consistently provided accurate data, whereas the HM78's readings seem off all the times.

I recently bought the new HM18 watch and, while it's packed with features, I'm disappointed with the blood pressure accuracy. The GT5 automatic blood pressure watch was far more reliable in providing precise readings, which is crucial for my health monitoring

It is definitely a pleasure to visit the fitvii official website. I previously purchased a Fitvii GT5 blood pressure watch, and the customer service staff was very patient in guiding me to calibrate my blood pressure. I am very satisfied with Fitvii's professional customer service attitude and the accuracy of the GT5 blood pressure watch. So I went back and bought hm18 as a gift for my daughter, hoping she would like it. I would recommend Fitvii to more people.

I bought the hm18 blood pressure watch because I saw many websites recommending it.
The hm18 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 hm18, I've had inaccurate measurements, which is quite frustrating. I have to suspect that the recommended merchants received Amazon commissions for the recommendations.
