LOOKEE Ox-Check Ring Wearable Oxygen Monitor | Continuous Pulse Oximeter with Vibration Reminder for Low O2 | Rechargeable Blood Oxygen Saturation SpO2 Tracker - Free APP with Reports

set this to vibrate if your o2 drops below any level you see fit. use your smart phone to see your o2 levels while you are wearing this device or later when you have time to look at your history. I have searched for this very thing for over 5 years and all the watches and gadgets from china never did what this one thing does! If you are worried about the corona virus then this will warn you while you sleep if your o2 is low. I don't know who wouldn't want one of these! You should buy one for everyone in your family. I am.

This product was used approx 20 times. Now no display and battery does not charge much.

Very helpful while awaiting consultation for possible cpap

I like thats is small and comfortable. I do not know the accuracy .

I can never get this product to read accurately for me.

I wound up in the hospital after forgeting to attach my 02 to my cpap. I went 8 hrs without 02. I was lucky to be alive. This product would have prevented this. Would have been alerted if 02 dropped

This O2 sensor seems to work well, but i keep knocking it off while sleeping. Maybe people who move around less during the night will get more use out of it. I have used it multiple times during the day to check my blood oxygen levels and it is very quick.

This device really helped me understand the kind of sleep apnea I have. It gave me peace of mind by prompting me to breathe every time I held my breath in my sleep.

Si tienes paciente en cama en casa, es un "must have", lo debes tener. Es un oxímetro muy pequeño y no se cae como los tradicionales, y el tema del resguardo de datos lo hace más útil aún. Yo lo tuve que regresar porque no tiene alarma auditiva, solo vibración cuando llega a los niveles que previamente estableces en la aplicación La aplicación súper fácil de instalar y manejar
