So great to have this reassurance that my loved one's oxygen level is where it should be! It does exactly what it's meant to do Works perfect

And she was just delighted to receive it especially after she had been saying how she wanted one

Works great, took it to our last visit to cardiologist and reading was the same as the ekg reading Works great for my mom with cancer My husband has found that this addition to his daily routine in the care of his CHF to be a great relief

Perfect and the price was right

y off but just 1% maybe 2% but you'll get that with these portable ones no matter what you buy I'd been quite sick recently and the nurse recommended I buy one of these

That's where your blood oxygen levels drop too much while you try to sleep
