The saturation measurement function is adequate, I suppose, after using it for six months. A result that is even somewhat close to reality requires at least three measurements. We validated the results by comparing the clock's reading to that of a medical equipment designed to gauge oxygen saturation; the latter reads 100%. I hope to find a non-silicone strap to order in the near future because current one is very distracting for me to use when sleeping.
