Within a short period of time, the screen shows nothing.

It broke with easy use .. Once a month thing. I opened it to see why it broke and the cables were so tight that even a small movement inside cut them off and they didn't make a circuit

First of all, I have to say that I bought it from a pharmacy for 20+€. At first, it measured with difficulty. Now it doesn't measure at all.. wasted money, stay away

I bought it from a pharmacy for 20 euros, it worked 1-2 times and now it doesn't record anything during the day anymore.. I got it supposed to check the oxygen and if I need something more than quarantine at home.. of course, it will be returned. I do not recommend it

In general, good!!!! Sometimes it doesn't make accurate measurements.... you close it, open it again, and it's fine.

At first, it was measuring but very low oxygen. That is, 92 to 90. We got scared. We thought we had coronavirus. We went to the pulmonologist and he measured our oxygen and it was 98. Within six months, it completely stopped working. We changed the batteries and still the same. It shows nothing. It is dead. I threw it away and bought another one from a store with orthopedics. I do not recommend it at all!

I bought it urgently from a Pharmacy for 22 euros, meaning it worked for me well, but what could I do, I needed it. So far, even though it is very slow, it shows satisfactory values, at least I believe so. I always subtract two units from the oxygen by myself for safety. As soon as it shows, for example, 96, I calculate 94. Do this in everything so that you can be sure that you are very close. Now, if I see something else along the way, I will throw it away, it's very simple, I will give it one star and that's it. For now, however, it's doing quite well.

My sister brought it to me because of Covid to measure my oxygen, she went and bought it from a 24-hour pharmacy for 20€ due to the weekend. The worst thing is that it measures sometimes and sometimes not, and I highly doubt the accuracy of the measurements it makes when it manages to make them.

It takes a long time to measure. Your finger needs to be warm and wiped before. When the reading stays steady, that's the correct indication. It requires effort and patience.

Waste of money! Unreliable. I tried it multiple times with a doctor's oximeter and it showed 10 units lower. Don't even think about buying it. Spend a little more and get something better for your health. Here, the saying applies: you get what you pay for!

Satisfactory but compared to the other one I have, it's a bit slower. We're talking about a difference of 3-4 inches overall, so for me it's not a big deal, but I felt the need to mention it.

Useless or defective.
It shows different measurements within seconds ranging from 92-97%.
Many times it doesn't take a measurement and shuts off because it doesn't detect the finger.

*****+ I would like to put and express a BIG THANK YOU to the skroutz team, as the first product I received in the morning was defective (these things happen) and after informing them and sending the photos, they immediately responded without me having to go through the process of returning the defective product. They sent me a new one, keeping me updated on the progress of the shipment. Thank you once again. And I have already made another purchase through your website, as I have done before.

Quite good! I can say that for its price, it is very good and so far it seems reliable in its measurements.
