My newborn is a month old and I've been using this product every night since we came home from the hospital. The video monitor works well and especially like the background audio feature. The sock/vitals is the reason we bought the Owlet after hearing a close friend's nearly tragic experience with their newborn that stopped breathing (story has a happy ending thankfully) and were lucky enough to check on their baby just in time and then calling EMTs. The thought of that potentially happening to our newborn at a time while we might be asleep is what led us to this product. We had some concerns of false positives and the alarms driving us crazy, and being more trouble than it's worth - but none of that has happened. Product works exactly as intended and has shown to be reliable. Check out a few YouTube vids that compared the SPO2 and HR accuracy against hospital grade equipment and it was spot on, so we pulled the trigger.
