Wearables Track Infants' Vital Signs - Would you use these devices?

Would you used these wearables that track infants' vital signs? I think they are expensive gadgets and probably unnecessary for the normal, healthy babies. However, I can see them being helpful to parents of children who have medical conditions.

What do you think of these wearables?

    I think they are cool only if you have a baby with medical issues but sadly these devices are usually not rated for medical issues. I worry about the frequency being emitted and if that could cause any harm to my baby.

    They would probably be more useful if they were rated for medical issues, at least for parents of children with health issues.
