Baby Basice Bottle Liners - 4 oz, ready formed, disposable, collapsible, pre-sterilized

Compared to rhe "name brand" they're the same thing to me. Only reason for 4, not 5, stars is because rhe box came crushed and we had a few issues with formula dining out the top when pushing the air out of the formula (after getting used to them we had no further issues). Worth saving some money if both offered under 'Prime'.

So far they look and feel about the same is say for the price it's a great deal would buy again

Of all the off brand liners I've tried,these are the worst. They would not stay on the bottle and I kept losing milk. I returned them. Just stick with the playtex brand.

I think they must be improved the design, because I had no issues with these ones. You can same quite a bit of money by going with these generics. For those that may be wondering, the idea behind bottle liners is not only are they sterilized for cleanliness; but as you push the air out of them completely; your baby will not get all that air into their little bodies. These have been our number one way to prevent colic in young babies.
