It should be withdrawn from the market! I wanted to know, aren't they ashamed to have such a product with consistently wrong measurements? What kind of things are these? I have had it for a year, but from the first month, the oxygen levels were "playing" with significant deviations in all the people who used it. And in terms of price, you can find excellent ones at the same price! Do not buy it unless you want to end up getting stressed.

One star for the good battery life and heart rate measurement. Do not trust it for blood oxygen! From the first month of use, its readings were completely unacceptable. It can easily cause concern. Stay away from this purchase.

I highly recommend it to anyone looking for a reason to go to the hospital. If I didn't find another oximeter in the family, I would have gone to the hospital with what it measures.

The Oximeter is a crying shame in terms of measurements. I had it replaced 3 times by POWERFARM and the only thing I positively evaluate is the service of the staff towards my problem.
The measurements of the oximeter are unacceptable.

The accuracy of it is tremendous....
The reading ranged from 36 to 99 and almost never stabilized.
Unreliable.

Every time I placed it on my finger, it showed a different measurement. It showed three different measurements within a five-minute period. It didn't seem reliable to me.

When it opens, sometimes, it doesn't show accurate measurement at all.
With Covid, it was giving me readings from 49 to 91, it sent me for hospital check without reason and finally the measurement was 97.
Stay away!!!!!!

Very fast measurement and reliable. It captures even children's fingers. Sturdy construction, no comparison to Chinese ones. I will get another one. Good price
