LOOKEE Health Ring Tracker, Oxygen Levels Heart Rate Monitor w Vibration Feedback Free APP for Sleep Fitness Sport Aviation Wellness Use

I have just received the pulse ox tracker. I compared with another pulse ox monitor on the same finger, but got totally different reading: the tracker reading was 91% on O2 with heart rate 62, but my regular pulse ox monitor reading was 97% with heart rate 70. Why do I know the tracker reading of 91% is wrong? I know 91% on O2 is severe hypoxic and happens in the patient who has pulmonary issues. The tracker is not acceptable and will give you wrong information, so do not buy it. Ask your doctor about your data then you will know it is inaccurate.

I was recently diagnosed with Sleep Apnea and was shocked to see how low my O2 levels dipped while sleeping. So I purchased this device to verify that my shiny new CPAP was indeed protecting me from brain damage (it is). Furthermore during a recent hospital visit I brought the device and compared it's readings to the hospital's. It was spot on, in fact it was a little faster than the hospital's by a second or two in detecting changes.

This one was defective and wouldn't stop vibrating. But it is a great way to tell if CPAP is working, etc.

I knew I have breath issue during sleep because of snore. It is still shocking to find out how low my blood oxygen is. I recommend everyone with snore issue get one of this monitor and treatment. It's very comfortable to ware.

Works great. Augmented my CPAP tracking.

Purchased this product in early 2019. It took eight weeks for the product to be delivered. Communication with the company was impossible. I had to get Amazon involved. Almost cancelled the order. After six months the little button that turns the unit on and off broke. Reported this to the company and no response.Great idea but poorly made.

The media could not be loaded.  Overall, I am quite impressed at how this sleep monitor is accurate. The ring is quite comfortable and accommodates different finger sizes. The app is simple to use. I love how this can actually track my entire spo2 throughout the entire night, whereas some fitness trackers have limitations to the data being captured.
