I also recently saw this post: http://www.apneaboard.com/forums/Thread-...d-to-OSCAR
And these wellue rings look pretty nice. Not too obtrusive looking, and it seems like it'd stay on my finger well through the night. However, it is one of these cloud based things, and aside from harvesting my personal data, the manufacturer could at anytime send out an update that would make exporting the data as the above poster did impossible, which would suck. I've had that happen with other tech...for instance, a security camera that after a firmware update no longer allowed you export video via usb to your device, instead you'd have to buy their subscription service to get the footage.
I looked at SleepHQ and all their gadgets. They do seem slick, but the whole cloud based data thing where I can't just store my personal data locally bums me out. I just hate that whole business model, it's very invasive. But maybe that's just the best/most painless way of pairing your O2 levels with your cpap data?
Any other O2 devices you might recommend?
