Simple but practical

Everyone should have one in their home to check for medical symptoms. I use them to calm my anxiety when I have panic attacks and feel like I can't breathe. It shows me my breathing is okay and I calm down. The reading results are accurate, I will buy more to send to my family

Product quality is better than price. I compared it to my more expensive oximeter and the results were the same. Overall, this is a great buy, especially if you don't have one of these then you should have them. I have panic attacks and these always help me see that I am breathing normally whenever I feel short of breath.

Very good. Great cost benefit. Sound tailing. I recommend it

Works well

Works properly. Is not known to lie or the truth is telling.
