Santamedical Generation 2 Fingertip Pulse Oximeter Oximetry Blood Oxygen Saturation Monitor with Batteries and Lanyard (Silver). (I bought this device in the black color) It comes complete with lanyard, batteries and carrying Velcro pouch. My sister and I both like this product. It is less expensive than big box stores and arrived promptly. Quick way to check oxygen saturation and one's pulse. Will recommend it to others.
