Good construction but not at all Good measurements. No matter what it measured from a child to an elderly person, it always showed over 20 pressure...

Compared to an arm blood pressure monitor, the measurements are almost identical. My mother, who often experiences palpitations, uses it and gets a reading, while others in the same situation show an error screen. It is very easy to use and easy to read. It has been incredibly helpful for my own needs.

You need to take 3-4 measurements and calculate the average. It doesn't come with a case. It's better to get something easier and more reliable. If you don't want to pay, you can get this and do the math.

It gives completely wrong measurements and when I contacted them to return the product, they wouldn't respond, unacceptable

Overall, I am satisfied with the product, the only negative thing is that many times if you measure again, it gives you different measurements (close ones of course, but I don't know how logical it is).

Fortunately, a lady wrote that she has a large wrist and I bought it because I couldn't find it anywhere else. It does indeed fit comfortably on a larger person. The measurement is approximately good, anyway we only use it for monitoring the wrist. The function is good, the material quality is 7/10, a satisfactory purchase for its price!

Just received it, I don't know yet how accurate it is, it seems durable and it is fast in its measurements, minus one star because it doesn't have a protective case.

Excellent choice for the money, it looks much higher quality than I expected and has a large wristband.
