Are Owlet Dream Sock readings actually reliable?

This is the most contested question in the data. Some parents on r/daddit and r/NICUParents credit the sock with catching real oxygen drops during illness, while r/BabyBumps and r/newborns threads flag inaccurate readings, false alarms, sock placement issues, and note that Owlet did not receive FDA clearance as a medical device on its initial submission (it later received FDA clearance as a wellness monitor). Treat it as a peace-of-mind wellness tool, not a medical device.
