I bought this O2 sensor because my Apple Watch app has been showing intermittent episodes of low O2 at night. I wanted something that would allow me to see how low and how often this actually occurred. This device does that and with the use of the app I can download the overnight history of my O2 and see what happened throughout the night. I do wish the app provided a "slider scale" so that I could see exactly when low events happened. The app does has an alarm feature that I wish could be turned off. I've got it set as low as I can and the vibration of the phone can still wake both me and my wife. (I put the phone in a sock or on top of something soft on the floor so that we don't get buzzed. I'm sure it's supposed to be a safety feature, but...

Resolving issues takes many, many emails with a turnaround time of 24 hours. Returning a product is close to impossible even when it is under the return policy.

Hi, It works, no problem. I'm dreaming of an oximeter that can be used under water for freediving training. The perfect one could also be post synchronised with Garmin connect as an external data field. We are thousands of free divers seeking for this product... best

The oring is a great tool keeping track of my sleep apnea.

It works and it is easy to use. I feel confident of the readings I'm getting.
