Bought this thinking it was also doing the blood/oxygen levels. This only does pulse and blood presure. It has a humming sound as it inflates the wristband and it is very sensative to how you sit and does error a few times if the wrist wrap is too tight or too loose. Overall i cant realy say this is an awsome product but it's a cheap product and it's close to what my doctor say when i wanted to check if it was accurate. So for this price it's ok but it lacks in features and reliability, you usaly need to do 1-3 trys until it gets it right without error.
