Do you have one of these Rings?

I am thinking about getting one of this things because my wife snores so much at night. I am worried that she has sleep apnea--can these rings help monitor for this stuff? I am unsure what the benefits of the ring are in comparison to fitbit etc. I don't want to spend the cash unless it is worth it---stay tuned.
