Great hair ties at a great price!

Perfect for my thin, fine, fragile hair! And they don’t leave kinks in your hair after an all day pony tail. Love em.

replacement for the old venting system

The old ones got old and the plastic got hard. So it started leaking every time we shaked the bottle. They need to be replaced when the plastic starts to turn yellow. The stores dont have the replacement.

Perfect for the BornFree bottle system.

Bought these as back up vents for our BornFree bottle system because some reviews had stated that they tear fairly easily. This has not been an issue for us yet but we don’t’ use the bottles as often as someone who is exclusively formula-feeding. Although I’m sure they will be perfect when we do need to use them. I like the BornFree system better than any of the Dr Browns or Playtex systems used with our older children.

Perfect match with the botton & nipples and harmless so that could use together with the glass botton for safe feeding.

Great design but doesn’t seem to last.

The Born Free venting system is a better design as opposed to Dr. Brown’s that uses a long tube that’s often difficult to clean. These come apart from the bottle easily and can be thrown in the dishwasher or rinsed by hand. The main issue I have with these is that the rubber gets damaged easily and causes leaks. If they made this more durable, it would be a 5 star product.

Great Product.

As expected, I bought these replacement valves for my Born Free bottle system which I LOVE. My baby hardly ever had gas! Now we still use the same bottles but graduated her to the drinking cup spout! Awesome

What can I say about it… I need it for my baby bottles and they are perfect and basis for them…

I like this feature on the bottles because it eliminates my need to keep pulling the bottle out of my baby’s mouth because the nipple collapses. It releases that pressure and really does reduce the air that gets swallowed.
