It's not worth it, most of the time it shows my oxygen at 80-87!! Only after 10 measurements will it show 97

I chose it because of good reviews... I give it 1 out of 5 because there isn't a lower option... the measurements, even though I know all my fingers. I had another one before and I have the experience of which fingers show and which don't... but here, it's different... all readings below 93 and most at 83 or 80... the device showed me as dead... I contacted them the first time, they said I wasn't using it correctly... but the second time, when I compared it with a pharmacy device and it showed 83, they accepted it... I asked for my money back from this particular store... I don't expect to get it back since they say it will be checked by the service first... and surely they'll say it's fine... I wish I was among the other 300... but for me, stay away... we're playing with our health.

It seems reliable. It was checked with a professional one and gave the same results. We don't play around with these things...

Everything is fine, the only thing that disappointed me a bit is that it does not save the screen orientation. When it starts, it returns to the factory setting. Other than that, very good.

It was used by 2 doctors I visited so it is reliable. Its construction is sturdy and quite user-friendly

If not the best, definitely one of the five best oximeters available. Accuracy, stability in measurements, build quality... Extremely, extremely good

I am satisfied with this gadget, however I am not a doctor, so I take it with reservations. It works well after 6 months of occasional use.

I had bought exactly the same one before and I didn't remember, so I got fooled a second time. As far as saturation is concerned, it is quite good, but as for the pulse, it's way off! In general, it's very expensive for what it offers, there are others that are more reliable and much better.

After 3 years of use, the screen brightness starts to drop and now, after 4 years of owning it, the screen shows nothing but complete darkness. I looked it up and saw that the same thing happens to many users. So the LED screen is basically useless, so don't buy it, it's a waste of money.

Get it immediately if you need it!!!! Accurate measurements of both oxygen and pulse!!!! I have changed two and this is by far the best!!!!

Given that it is a commercial finger pulse oximeter, it provides the most "consistent" and stable measurements - and the greatest convergence with medical equipment measurements - compared to other finger oximeters I have used (3-4 brands, purchased from pharmacies). Having - unfortunately - gained quite a bit of experience in the field (equipment for saturation measurements with parallel pulse measurements), I can say that for us it is an essential daily tool. On the plus side is the build quality, as it feels more solid/stable/quality in touch and use compared to the others we have tried. For a purchase of 20-30 euros, you don't need anything more - proceed without fear.

It seems like a very good product. I have had it for a week. I believe the measurements are accurate both on the oximeter and for the pulses.
Reliability will be seen over time.

So far, I am satisfied.

I bought it for personal use, as it is now an essential accessory during the covid era. It seems to have accurate measurements and the construction appears to be of high quality. The company is well-known and I had noticed it with private doctors.

I bought it for my father; it doesn't delay in measurement compared to another one I had. Quite a few visual information compared to others.

Accuracy in measurements, cross-checked with a medical monitor in the hospital.
It was also compared to other oximeters, proving that they are useless for any measurement, unlike this specific product, whose measurements matched those of the monitor throughout the entire useful range of measurements (from 75% oxygen saturation of the patient to 99%).

This specific oximeter seems to be of good quality construction. It shows 1 unit of oxygen lower compared to another home use oximeter that I have.

Also, pay attention to battery placement. Until now, all devices I have used that require batteries expect the (-) of the battery to be on the side with the spring. In this specific oximeter, one battery must be placed with the (+) on the spring!

My parents have been using it frequently for over 1 year. The battery is ok and the device works immediately and satisfactorily. I think it's worth the money.

It is the 4th oximeter I have purchased and it is the only one that shows accurate measurements even in children (4 years old) with a little careful finger placement. It is relatively expensive but for me, it was worth it because of the child.

I bought it to monitor oxygen saturation after a serious health issue and hospitalization. Its measurements are accurate, the same as those from a pulmonologist (+-1). It is easy to use. You simply place your finger, stay still, press the button, and wait a few seconds for the waveform to stabilize. It has an indication for measurement error (question mark "?" instead of the battery indicator). It turns off automatically after removing the finger. It has instructions in Greek and the display indications are legible. I also consider this company reliable, judging from the blood pressure monitor I have had for years.

Quite reliable pulse oximeter, quality construction at a relatively good price.
It measures oxygen, heart rate, PI, and shows the waveform of the heart. It has a battery indicator and turns off automatically after measurement.

The one I got now does not have excellent measurements, so for its price it is very expensive. I had a previous one with excellent measurements and that's why I ordered this one too. For the new one I would give 3 stars, for the old one I would give a perfect score but due to the price I would give 4 stars.

So far, with professional use (in the pocket at the hospital for quick measurements), it has been excellent. It has proven to be durable and quite accurate.

Excellent machine! I bought it for home use, especially because of Covid 19. Its measurements are generally accurate, although sometimes it shows slightly lower oxygen levels by 1-2 units than the actual ones. However, the measurement of heart rate is excellent. As for the construction, it is a bit narrow and may be difficult for someone with thicker fingers. Nevertheless, it is a reliable choice. I would buy it again.

After 5 years, the numbers appear faint, with brightness at 10 (full). At night, it's okay, you can see something, but during the day, nothing at all.
Nevertheless, the indications are quite reliable, for as long as it lasted... That's why I'm giving it a second star...

28/12/22: I don't have anything to compare it to another oximeter, so take my words with a grain of salt, but so far it's working fine. I have no complaints. I hope it doesn't show below 95-96% oxygen because that could be a problem. If needed, I will come back.

This specific oximeter is very good, I say this because I bought another one from a pharmacy for 30 euros, from a well-known company.

We have had this for 2 years, it works very well. In my sitting position, I have 98 oxygen and 85 pulses or 74 accordingly. (And with the use of cortisone, it reaches 100 oxygen and 78 pulses).

While with the other one, it is so fake and plastic, after going through Covid for 2 weeks, it showed 94 oxygen and 68 pulses for everyone, it showed the same. So when I saw that I can buy it again from here at this amazing price, I got excited. Because they bought this specific one for 30 euros from a supermarket and yet it does the same job, very good, well done.

It does exactly what it should!!!
Accurate measurements!!!
The price is very good for the quality of the company!!!

Hello..after 1 month of daily morning use, and verified by a doctor, the deviations are > oxygen + or - 1 to 2%, and blood pressure + or - 5 to 8%, at the exact same moments...time will tell..the conclusions are yours..initial estimation= I consider it, very expensive for what it offers..

Due to covid, I proceeded to purchase this specific oximeter. It shows good results so far and the measurements do not differ from another borrowed one I had. It is a good purchase, but keep in mind that there are also more affordable options that may be equally valuable.

It shows reliability as I measured my father's oxygen a few days after the doctor had measured it and it was at the same level. Its operation is simple. Very useful for those who have lung issues, rapid heartbeat.

Update: During a visit of my father's pulmonologist at home, I compared the result of our oximeter with that of the expensive professional portable oximeter of the doctor. We had a two-unit deviation in our measurements, which were taken with a very small time difference. As he told me, this is an expected difference. And with the same oximeter, if I repeat the measurement twice, I get values with a deviation of 1-2%.

Therefore, I consider it reliable, value for money, but when I take the measurement and see a borderline result, I always keep in mind that there is a possibility of a 1-2 unit deviation and I am on alert!
