Owlet smart sock

Owlet smart sock to monitor baby's heart rate and o2 levels while they are sleeping or awake. I have the closed toe socks and I have the open toe socks as well like new condition. I thought I would use it more than I did due to my baby being in nicu for a period of time. Will connect to wifi and more than one parent can monitor at once ( my husband did at night while he was at work and we slept)
