O2 Ring vs Checkme O2
I am in need of a fairly fast decision about this. I mean, not in the next hour, of course.
Connection to OSCAR would be nice, but not a deal breaker.
Is the Checkme worth the extra money? I am considering it because the battery life is longer and I can wear it while awake as well as when asleep.
I can find a lot of reviews but it is this place I trust the most.

The Checkme is a SleepU on steroids. Consider this, both the SleepU and Checkme have the electronics as a wrist wearable unit. The O2Ring has everything all on your finger. This makes the O2Ring's finger weight more than the finger probes for the other two. All allow 4 10-hour sessions before rewriting the oldest file.
I probably added more doubt to your decision. I'm happy to help!

I have both, I wear the o2ring

Why yes, yes you did you snot.
And the weight on my finger is a concern. I'm thinking I would take it off in my sleep. I often did my old clamp one.
The 10hr session is a concern. Since I often go to bed and lay there waiting to sleep, those hours would be wasted. Then when I do fall asleep, I tend to wake up, stare at ceiling, then fall back asleep. Being "in bed" for 12 hrs is not uncommon.
Well crap.

You disappointed me. I was expecting a "Bless your heart!".
When a 10-hour recording session is reached, it will start another session. There is usually a small-time gap between them.

According to the docs the checkme has a higher sample rate and much longer battery life. When I got mine it said the sample rate was 1 second, the newer one says 2 seconds, but the sample rate being higher has been disputed on here several times.
I can only conclude there are several versions of the checkme. Part of that being when I hd issus with the wrist strap they sent me a new one, but had to verify the model ahead of time, then they still sent me the wrong one for free. The newer unit is slightly smaller and quotes a 2 second sample rate, but seems to only record 4 second averages.
The O2ring quotes 4 second sample rate. I am not sure what it averages to for reporting.
That said, I turn the vibration rate to max, but turn down the alarm to 40 for pulse and 82 for SpO2 so it doesn't go off unless there is something worth waking me up for.
Where the ring sits right up against the hand the weight is far less noticable than the tip of the finger monitor.
With the vibration turned down/off neither I nor my wife take it off in our sleep.

The sample rate could well be 1-second, but it only records an entry every 4-seconds. I can't say if this is an average of the 4, or every fourth sample.

In any case, engineering folks want as high a sample rate as possible, but in my opinion it doesn't matter if the sample rate is 1 second or 10 or 4 second averages. But really how fine grain is actually of note or use?

RE: O2 Ring vs Checkme O2
With the four second sampling rate of my Wellue OxyLink (same as the O2Ring as far as the exported data is concerned) I can see a very clear correlation between my Minute Ventilation and oxygen saturation waveforms, as well as desaturations that happen as a result of apneas (with a thirty second delay), so although I would prefer a higher sampling rate it seems to be roughly adequate.
Not sure a ten second average would work, but you clearly don't need super high resolution data for it to be at least somewhat informative.
RE: O2 Ring vs Checkme O2
Sample rate is totally dependent on the variability of the area of interest. Consider measuring the temperature of the ocean. A sample rate of an hour would be over sampling. Getting back to the relevant topic. O2 levels do not change that abruptly. Consider the body as an O2 storage cell. Also, there is a latency between the actual cause for the drop and its reporting. Pulse, arterial flow, and the distance between the lungs and the sensor play into this, too. On the other hand, if your major concern is pulse, then oximeters are not the device to use. A recording ECG is the proper monitoring device for this.
