Santamedical SM- 150 is a super Finger Pulse Oximeter. A perfect way to check your pulse. It is small, lightweight, and easy to use. Great for people who suffer from Asthma, COPD and other breathing related diseases. I do suffer from medical issues and this is perfect for me to use. It is so easy to use, just install batteries place your finger inside and within seconds it will give you a reading. It reads your oxygen and pulse levels very quickly.
Readings are very accurate which is most important. It came with a nice case and it is of high quality. I received this product complimentary in exchange for my unbiased review. All words are my own.
