Easy to set up and use
Setup is easy, comfortable and not obtrusive to wear.  The buzz notifying the wearer of a drop in oxygen can be annoying to the sleeping partner, but it is easy to turn off.  Not sure about battery life; it seems to take forever to charge up.  Mobile app is easy to download, device easily and automatically transfers the night's data to the app/phone, and the readouts are easy to understand.  Overall, this is exactly what we were looking for and it provides good information.
