I use this product to measure the oxygen in our blood and pulse. This is reliable and efficient. really great and easy to use in family with its basic knowledge.
it does what it suppose to do.
I've heard some debate on whether home O2 meters are worth buying, but my take is something is better than nothing, and it gives a frame of reference. This particular unit seems to be fairly accurate.
