item received as described

Bought this one for me during the height of the pandemic, and bought a different make and model for my mom, I tested both for a brief period, and both were within range of each other. This one is easier for seeing your stuff yourself.

Bought for my dad who has pulminary fibrosis. He loves it for measuring his oxygen.

there were instructions for easy use. Batteries were included.

This has worked well. Not much else to say.

Quality product

I had a different one and I had a feeling it was off because every time I went to the doctor, they told me I was well within range. Not according to mine at home! This one was exactly the kind my dr. had so I got it. Yup, accurate too now!

Easy to read and understand display for oxygen and heart rate

That it works well
