I have used both summer infant and halo.
I was using the summer infant swaddleme for my son from newborn to 2 months. It can swaddle the baby nice and tide. After that I change to hola two way sleepsack coz the S size of swaddleme not fit him anymore.
The hola two way sleepsack can last longer coz you can let baby arms out when your baby is older. So far I love both of them!!
