Owlet baby sock??

Winter

My lil boy is in NICU right now and I'm currently looking at maybe getting a owlet sock when he comes home for peace of mind. Has anyone used one? If so what was your experience with it?

My lil boy is having problems with his oxygen levels and I now I'm going to be parnoid when he comes home and I was just thinking due to it montioring his oxygen stats that it might help. Any suggestions would be wonderful. Thank you in advance.
