Very thick bags compared to other brands; definitely don't have to worry about bags leaking. But the bags seem to not lay flat and freeze as well as Lasinoh bags; take up more space in freezer.
Update 7/22/17: just using up the last few bags in the box today. I was about to pour milk into a bag and noticed some metal flecks/flakes inside. Threw that bag out and then examined the last bag -- same thing. This worries me because the flecks/flakes are so small and I am worried that I didn't check previous bags carefully! Now I will have to examine each bag before I feed to my baby. I don't understand how the flakes got in there since they are sealed -- must have happened during the sealing process at manufacture. Won't be buying these again.
