Owlet sock thoughts???

I was in a baby care class and the instructor did notttttt recommend the sock at all. She was very much against them actually. She said that most babies are fine and all it causes is the constant stress of monitoring your baby’s vitals. I personally feel like it’s a pretty reasonable “stress” to put on yourself being that it is like a third set of eyes and then some.

Does anybody have any experience or perspective on them?
