This little device is very easy to use and looks like it will last a long time. You get immediate readings for oxygen saturation and pulse. I do not have another device to check for differences in saturation accuracy, but I have checked my pulse with my blood pressure meter, and the pulse readings between the two have been very small, within two or three beats per minute.
