No Worries of Frequent Charging

Rechargeable battey, 72 hours battery life. Continuous tracking for 9 nights after one full charge of 2.5 hours.

Remind You to Breathe Well

A normal range of blood oxygen level is the key to starting a new day. During the night, when your SpO2 started to fall below the preset value, the prompt will be activated. Unlike the traditional sound alert system, it softly wakes you to change to a position that helps you breathe better. So sharing a bed with your partner won't affect his or her's rest. Checkme O2 ensures you wake up with an energetic morning.

Vibration makes me go right back to sleep

This wrist helps me a lot. I have sleep apnea. The device will vibrate and sound when my oxygen level drops and I can turn on my side. I am able to go right back to sleep.And in the second morning, I can feel more rested and no headaches,

Great device helps a lot

I use this o2 band to easily monitor my oxygen levels and really appreciate the alarm to help me not drop to low. I would recommend this unit to people with Lung, and Sleep Apnea problems.
