The material of the bottle seems cheap, but it does the job, you can squeeze the bottle to increase the flow.
I bought the SNS for my 8w baby to help him latch without nipple shield. It worked very well. I only used once a day for three days. A few tips: do not close the bottle super tight or you can break the seal; wear a nursing T-shirt that can hide the tubes under, so your baby does not pull them out.
