When you used these, did you have the vent on the born free bottle to prevent leaks?

No I did not. Pumped right into the bottles then assembled the bottles when I was done.

No, the adapter just screws on to the bottle and the attachment pieces from the pump. I had no leaks. However, I didn't use it for long due to the bottle. I used glass instead of plastic. Glass was heavier.

No, the vents are only used when feeding baby. You just screw this onto the bottle and the breast shield for the pump. I had no leaking problems.

No, at least mine weren't. We bought 10 and half of them leaked the first time we used them.

I did. I put in what I could fit and then the rest when the oil was low enough. I know for sure it can't hurt and it's not that expensive. I bought extra bottles in case I need them but so far I haven't. Hope this helps you. Ami.

No they do not. I use the Born Free bottles right now for my 4 month old and you have to buy the born free nipples. These Medela nipples are very small and only fit the smaller Medela bottles. I do like the Born Free Bottles and would recommend using them.

Yes. According to my wife, they worked as well as the older/smaller (in width) 5oz bottles. Some reviewers had issues with leakage, but there wasn't any leak when attached.

We have found if the hole is on the top nothing comes out for my baby. We have not had leaking but she don't get anything if its the wrong way. I love these bottles my baby goes breast to bottle and bottle to breast with no problems. And I think an older baby would prefer the bottle the correct way and have no problem self feeding.

No, I didn't have a leaking problem. My does not work. I believe they cannot be plugged in all the time however I'm not sure.

I don't know, I've never used born free bottles. Sorry I can't be of more help!

I have had no issues w/ leaking yet. I did use pipe tape to help the fitting to better seal. So, I have not even bothered getting a fitting as mine has been fine

Yes, but as far as I'm concerned about half of them leaked. The grommet that goes into the bottle was not a very tight on the actual metal of the pourer. I would recommend buying something of a little higher quality.

I'm not sure I understand your question, but yes, the Born Free bottles that these Venting Systems are for, are indeed wide mouth.

I have four rain barrels and vented the first two because we thought they would need vents but after the barrel filled with water they would pour water out of the vents, the second pair of barrels were not vented but the filled to the top with out a problem so I feel that the vents are not needed !!

Since the relief valve is internal, it does not vent to the outside. It simply prevents you from over pressuring the bottle. I am happy with the product.

Well- in 2010 we bought bottles for my daughter. Had no need to replace any parts for her (1.5yrs). In 2013 pulled out the bottles for my son. Noticed leaky bottles & realized that the tiny slit on the vents had tears. Replaced the vents and had no issues since then.

I have not had an issue with leaking yet. Have been using one for about a two weeks so sorry will know more in a month or so.

I am not sure, I did not ever try born free bottles. We ended up with the Evenflow glass bottles and were very happy with them.

No, sounds like something isn't in tight. I've never had a problem with any of mine leaking. Give the company a call
