Husband would like to know the oxygen saturation level in the blood at times that is why it is being purchased. With so many device of the different brands to choose from and the different price ranges, I did the best I can. As it turn out, the product I purchased is great. It is easy to use, the lighting that show results are clear and easy to read. The price is reasonable and it is price average as compared to similar product. I especially like the outer cover which help protect and keep the product safe when not in use. Yes, I would recommend this product to others.
