Four times the cost of regular oximeters for arterial testing that simply doesn't do it. On each finger and a different measurement from 1 to 4. The screen, after 7 months of use with one measurement per week, stopped lighting up and no matter how many batteries we changed, we couldn't see any light. People laugh at their service. If you find it, let me know too.

Whatever I say about this product will be little, you understand it as soon as you hold it in your hand, very good and compact construction with clear indications that rotate 180 degrees for the examiner/examinee to see them. It serves very well for people who have asthma or other respiratory problems to know when the patient will need hospital care or not.
I really liked the specific system that evaluates your artery condition, especially for men who have heart problems.
It comes with an orange cord if you need to carry it on you.

I leave the review so that we don't waste our money seeing "generalities" in other reviews. Initially, as an oximeter, the device is very good. That is, it shows oxygen and pulse correctly. However, the arterial control (ACT) that it is supposed to do, and for which it costs three times the price, is completely unreliable! I measure it twice on the first day and it shows 2. I measure it the next day and it shows 3. I measure it the next morning and it shows 4, and in a short time it shows 1! Then I did the same by putting and removing my finger and it constantly changed from 1 to 4. So, what it is supposed to do more to prefer it over another good oximeter that costs 30-40 euros, it doesn't do it! Also, the button, no matter how much you press it, does not turn off the device as the instructions state...

Excellent plastic construction and readable screen.
The only oximeter that also shows the condition of the arteries.
I recommend it!

I bought it and it is very stable in oxygen saturation. The only one with blood pressure control functionality. I recommend it!
