Maymom Replacement Baby Bottle Nipple Rings for Philips Avent Bottle, Compatible Screw Ring Collar for Avent Natural Plastic and Glass Bottles; Not for AntiColi Nipple, BPA-Free, Secure Latch, 4-Pack

This was well needed. My daughter did not like the anticolic nipples so needed different screw caps to work with the nipple. Super easy to use fit perfectly fine doesn’t leak. There’s also a convenient lid to storage and travel with premade milk. and overall performance is amazing!

Used with evenflo nipples on avent bottles. Worked like a charm

These were a perfect fit for the Avent collars & no leakage! They are easy to pop in & out & clean & has helped improve the amount of milk I can store for on the go or just in the fridge until I have a moment to bag & freeze. Came in a pack of six & was very happy with the price & quality.

Got these for my glass Philips Avent bottles that I plan to pump into and store milk in. These click perfectly into the Avent caps. Easy to clean and use. Good value for money.

Bought bc we were tired of searching for and cleaning lids, fit perfectly and we can't even tell the difference between the originals and these ones

the screw rings worked perfectly and we no longer have any issues with spilled milk. however, these caps? horrible. not sure if it’s bc i sterilized everything before using or what but they were on so ridiculously tight that i had to use a knife to pop them off half asleep in the middle of the night. i’m so glad i kept the original caps just in case.

I bought this set to go with bottles for my Spectra pump (these work with the bottles the pump comes with as well as Nene bottles from Amazon that all connect to the pump). Initially, I only washed and steamed them in my microwave device. They leaked immediately. I then read reviews that you need to actually BOIL THEM to fit properly. So I boiled them for 4-5 minutes and they’ve all been perfect ever since. No leaking. No issues. I also read that you can strip the tracks if you over tighten them, but I just wonder if this occurred because people tried to correct a leak if they didn’t boil them. I don’t find myself feeling the need to over tighten them, I just screw them on normally. I would buy these again! Just BOIL THEM first!

These are really great replacements. I would say, they're even better than the original rings. No leaks yet! The caps were very tight, but if you sterilize the lids on the collars, then tension is just right!
