Bests & Worsts Reviews from Amazon

Highly recommend! It calibrates perfectly with my Dr's oximeter. When Dr said I should get one to monitor at home I was afraid the cost would be too high but when I did research on Amazon I was delighted to locate the quality of this unit at such a low price. Plus the wonderful convenience of being able to have it delivered to my house instead of having to find someone to drive me to locate a medical supply facility. I've had it for a month and it has really given me peace of mind knowing what my numbers are on a continual basis.
