Quite economical and reliable oximeter that agrees with the readings of my smartwatch. The battery has a long duration.

I bought this oximeter for use in my work. Unfortunately, from the beginning it did not accurately show oxygen saturation and it took a long time on the finger to show correctly. Furthermore, it soon started to malfunction and consume batteries within a few days, resulting in me having to change them every week! The previous oximeter I had was the same and I had not encountered the same problems, which is why I chose it again.

Compared to another oximeter that I have in my possession, I would not say that I was satisfied with its measurements.

I have nothing to compare it to with any other oximeter, but I have the impression that it works correctly, its measurements seem okay to me

I had ordered a different brand but they sent me this one. Unfortunately, it does not have any reliable indication. 8 out of 10 times it shows 96% and 2 times out of 10, 98 to 99%. The indication with the hospital oximeter is always 99%. The only thing that works is the pulse indication, it always shows the arrhythmias.

Tragic measurements! It constantly measures all of us in the family from 88 to 96. (The other oximeter measures 98 to 99). Sometimes it even shows 80!
Unacceptable!

If you don't want to lose your sleep, don't buy it. It shows 96 but drops you to 80, whatever, stay away

It is okay in terms of construction and measurements, although I am not sure if the measurements are accurate, as I use it for household purposes. What bothers me is that many times it does not give a reading no matter how long I leave it on my finger, so I have to take it off and put it back on for it to work

For its price, it's OK. Easy to use, the measurements don't seem to be far from reality (sorry, but I don't have a professionally calibrated oximeter to compare), the screen is clear, and its construction is OK.

In about a year, I used it twice, so I don't have an opinion on its durability over time. Obviously, it needs a little attention because all its parts are plastic.

For personal use, it's fine! The results it produces are quite reliable, just sometimes if you leave it on your finger for too long, the oxygen may start to decrease... as for the heart rate, I wouldn't say they are completely accurate! Other than that, it's fine for the money if you want it as an oximeter!

Cute Pulse Oximeter. It needs a little adjustment to be able to catch pulse and measure. Sometimes it has crazy measurements. It needs to be properly placed first and then wait. For some, this will be difficult.

It has a nice screen that you can orient in 4 directions. Whichever suits you.

For its price, very good!

The measurements have small deviations. The construction appears to be of good quality. On the downside, many times it cannot complete the measurement, as it loses the pulse for some reason and you need to insist a lot to make a measurement.

Although it appears fragile, the build quality and the usage so far (2 months) seem satisfactory. The measurements are done quickly and appear relatively accurate compared to other devices.

The evaluation is done only regarding ease of use and measurement speed. I do not have the ability to evaluate the accuracy of the device's results, but the results it provides are logical.

It is excellent. I would buy it again.

Measured the pulse once and never turned on again
The battery door did not close
And this one measurement it made was wrong
I do not recommend it!!!

It seems reliable in terms of its measurements, at least regarding heart rate. I have checked it with a blood pressure monitor and they measure the same. Now, as for oxygen measurement, I don't have an opinion. However, it has a fast response. I recommend it

It shows different from others. I have experienced the actual saturation to be 94% (measured in arterial blood gas) and this one shows 98% one time and 88% another time. No reliability. I threw it away and got another one.

Maybe the more expensive ones are more reliable in measurements!!! However, it seems to measure correctly most of the time with small deviations!!!

It looks good, but it shows me, for example, from 95-97 and it confuses me. I don't know if that's how everything works. I have to take it to a pharmacy to compare it with another one.

Half the time we go to take a measurement it's impossible. Unfortunately, I was swayed by the positive reviews and bought it, but in our case it doesn't work properly.

I received it, the screen turned on but it didn't take measurements. I returned it. I don't know if this specific product happened to be defective.

Easy to use and small (easy to carry!). We have tested it with another one and it measures oxygen perfectly!! Sometimes it shows higher heart rates than it actually is but not to a scary extent. If it is for use on a larger person, get something with more accuracy!

Good device, for its price. The battery door does not fit well in its place, it seems to come out very easily and does not fit properly, but it can be fixed by turning the battery contacts backwards. (photo). For those who the machine does not count, "rub" your finger for measurement!

Good device, for its price it is a decent oximeter, however, I would still like the battery cover to fit better in its place, it seems to come off very easily and not fit properly.

It seems to work just fine, we all did a test in the family (young and old), easy to use, it gives the correct reading after a few seconds by keeping the finger still on a stable surface. It may be unnecessary, but we got it just to have it.

Reliable genuine contec with 2 EU certifications, with a two-year warranty, with a strap and a hanging case for the belt, the best available in the market, price 26 euros

I bought two pieces, and they both have the exact same malfunction compared to another certified one that I operated at the same time. So both machines were showing the same oxygen level, 93%, while the certified machine showed 98% oxygen, and this specific difference is not just critical but vital.

Simple and honest machine. It does its job satisfactorily, whether for amateur or professional use. You get what you pay for.

Very reliable in its measurements compared to others I had bought. I bought it for 25 euros instead of 35 and 45 that they sell it with a case, batteries, and a strap. Beautiful aesthetically, good with many certifications from the best
