Bests & Worsts Reviews from Amazon

I Purchased this Pulse Oximeter fingertip blood oxygen saturation monitor with pulse rate measurements and pulse bar graph. It arrived today and my wife and I tried it out. It works fine and is light weight. I am 69 and find the numbers and graphics readable, but I would have liked them slightly larger. The only negative is the tiny holes for attaching the lanyard. Overall we are very satisfied with the product.
