Review on 🩺 Wearable Health Monitor: Wellue WearO2 - Bluetooth Pulse Meter with Free APP for Continuous SP-O2 & Heart Rate Tracking by Jesse Hughes

Highly recommended. I had a double lung transplant 25 years ago. I have used many pulse oximeters over the years. For the money I haven't used anything that can compete with it especially for tracking SPO2 and HR while sleeping that is so compact and comfortable to carry. he will NOT fall. The rubber finger grip is very well made (I wear it on my thumb). I didn't want to spend another $4000 on a sleep study (that's the price I had 5 years ago). After a week of use it's all clear to see my O2 dropping to mid 80-x too often and for too long and that's why I feel like I'm not getting enough sleep.
