everything is fine....I believe it is excellent for its price..... after measuring with a different, more professional one, I saw that it gives the same results ....

After a few months, it started showing random readings compared to a good blood pressure monitor and now it almost doesn't work at all. It lasted barely a year, with relatively light use.

The measurements are relatively accurate but I always have to use it more than once. The very negative aspect is that it takes a very long time to take a measurement and the batteries run out quickly.

This is the second one I have, very good accuracy in measurements (compared to the Omron blood pressure monitor) but the only thing that bothered me immensely was the constant 'beep-beep' with the heartbeats. This is solved by pressing the button as soon as the measurement starts and it immediately stops forever!
Attention: when your finger is cold, e.g. you just came inside from outside, then the first measurement will be incorrect (it will show very low heartbeats) so either rub your finger a bit to warm it up or wait a little while for your hand to reach room temperature before measuring.

I use it for professional use daily on bedridden patients. About 50 measurements daily, 20 days a month, and the battery needs charging every 2 months. It measures quickly, accurately.

It couldn't be more accurate.. it saved us with the baby who had low oxygen. He was months old and we put 2 fingers in to get a reading

The best pulse oximeter, two years of daily use by a patient with COPD, and it hasn't suffered any damage, amazing accuracy.

I can't be sure that its measurements are accurate. Of course, with such oximeters, you always have to take measurements 2 or 3 times to be sure

Unfortunately, the results it produces are far from the results of another machine I have and the smart watch. The battery drains quickly.

It does its job well, I have bought it twice as I got it for a relative as well. I consider it value for money for what it offers.

Average accuracy in O2 measurements and it's a bit slow. You can't really trust it in a difficult moment. It shows the pulses just fine. Also, it's a bit fragile.

After a while, it takes time to get measurements. Generally, it's not bad. Just for everyday use, it's not worth it.

Reliable as you can see in the photos...of course, it's better not to upload them because the price goes up too.

For the money, it is quite good. There is no difference in measurements compared to another one we tested. The only negative I can find is that sometimes it doesn't catch immediately

I had bought it several years ago, 17 euros. I have been quite satisfied, I compare and it gives accurate measurements. I would recommend it and I don't think anyone who buys it will regret it.

It seems like a good product, but I don't have a point of comparison to know if it provides accurate measurements and give it a 5-star rating.

Affordable oximeter for personal use. I bought it for €10 for my father after a surgical procedure that required monitoring his pulse.

For home use, it is value for money. I have had it for at least 2+ years, it hasn't had any issues! I recommend it.

I am satisfied with the purchase, it has good battery life and I bought it at a good price.
In cases of tachycardia that occurred to me, it simultaneously produces a second, intense audio signal.

He seems to be doing his job just fine. I don't know if he has any exclusions from a similar professional product. Surely, if we see a strange measurement, we will definitely consult a specialist for an accurate image.

Very satisfied with this purchase.
Reliable and I found it at a very good price (pre-coronavirus).

Very good for its price and accurate in measurements. I bought it for my father who has been measuring himself two to three times a day for a year now. He is very satisfied. I also bought a second one for backup

I relied on the good reviews and I was fooled. The machine is whatever. It shows pulses that have no relation to reality (I was measuring the pulses simultaneously with another oximeter). It's not worth a dime.

You need it, but when you need it, it is necessary, and its measurements must be accurate. It seems to do its job and its indications are clear on its small screen.

Cheap and effective, for its price the battery and its measurements are great. Now, if you want 100% accuracy in measurements, you should pay a little more. For the 9 euros it costs, it is very decent.

I think it is the ideal best value for money.

Every time we measured, it had reliable and accurate measurements

A great tool, clear display, had the battery included in the packaging, and accurate from what I could judge.

It was good, as long as it worked. Within 3 months, its indications are almost always wrong. It's better for someone to spend a little more money to get something better.

Due to covid19, I also entered the anxiety! Because it first affects the decrease in oxygen, it was tested and so I decided to get it for the whole family and have it at home! We have 3 in the family and there is absolutely no problem with either the measurements or the quality of it. I consider it top and at a very good price for home use.

It does not seem to be perfectly accurate in its measurements.
Also, its batteries seem to drain quickly, as after about 20 measurements, the characteristic sound of the heartbeat is no longer audible but only gives a visual signal.
If needed, I will probably resort to a more expensive (and hopefully higher quality) solution...
