Very good choice, I highly recommend it for personal use. The store's service was exemplary!

Very bad product. The store sent me the wrong color (pink) and overall it doesn't work at all on patients. It can't measure. Even on my own finger, which I don't suffer from anything, it takes a long time to show any indication. Very bad purchase, I wouldn't recommend it to anyone.

It seems to work accurately. At least for the pulses that I can count manually.

Do not buy it... it broke like a walnut shell when I tried to change the batteries (the metal wires came out along with the old batteries). And before that, it was a very sensitive device and took a long time to take measurements. Now it is completely out of order...

Necessary for the family, for small children and adults.
Think about being able to prevent earlier a bronchiolitis-bronchitis-allergic shock, in children, when you use it and see the low oxygen. Common symptom of all these is difficulty breathing. So we don't waste time and go straight to the hospital. Because our little ones can't speak and tell us how they feel. It is truly necessary!!!!!
