Have no difference in the measured values to other, more expensive, may find devices. However, it takes about 1-2 seconds longer to determine the values. The spring is a little too weak when the patient moves a lot. The "Display" is reminiscent of an old clock radio, but it is clearly legible.
It is nice that the device is delivered in a sturdy box and works with the supplied AAA batteries.
All in all, I am fully satisfied. Differences in quality to more expensive devices are visible, but the values are correct and do not even cost half.
4 stars for the device, 1 Star bonus for the low price
