Owlet Baby Monitor

Smart sock + base that monitors baby's oxygen level and heart rate up to 18 months. My cousin just sent me the link on Facebook.   
https://www.facebook.com/OwletBabyMonitors/videos/723734747726523/. Looks like a pretty genius idea. I worried so much about SIDS with my first. I was constantly waking up at night just to check and make sure he was breathing. It's kinda pricey at $250, but the peace of mind it promises is priceless! I'm wondering if you ladies have ever heard of this? Even better if you have one and can tell me what you think!
