This is in perfect condition. I purchased for my dad and he didn’t end up needing it more than a night.

Vibration & Audio Reminder】The oximeter vibrates and keeps making a "beep" sound if O2 or PR level falls below your preset level. Vibration and sound intensity can be adjusted.

【Comfort Patented Ring Sensor】Wearable soft silicone ring sensor won't make your finger numb and never slips A from your finger, which completely frees your finger.

【Long Battery Life】Up to 72 hours of use after fully charged. No AAA batteries required
