Get More Use Out of Your Bottles
This straw cup conversion for the Philips Avent bottles is amazing! My 9 month old had been using a honeybear cup that wasn't spill or leak proof, so I was looking for another straw cup solution. We also still had a handful of glass bottles that we weren't using anymore because baby had been refusing bottles for a few months (breastfed). This straw conversion fits and works perfectly on our 4oz bottles! There's an extra amount of straw down in the glass (see photos) because I believe they're intended for the larger bottles, but that hasn't impacted their functionality, especially since they are weighted. Very easy to use - this pops into the bottle screw ring, where you'd normally put a nipple. The handles on the side are easy for baby to grasp and hold on their own. These have a valved straw, so they don't leak. They're are a little annoying to clean, so I wash them in the dishwasher and they've held up well so far. It's been 10 days and I've been washing them once a day. My only real complaint is the price because I feel they are expensive for what they are. But I'm happy to be getting use out of our glass bottles again!

Our go to
We use the glass Philips avent bottles so we got these attachments for cabinet space and they are the only ones our 1 year old will use. They were very easy for him to convert to from the bottle. Easy to clean, have had no issues with leaking, great for minimum space when stored. Plan to purchase more.

Great product!
Honestly i never write reviews on anything unless i feel very strongly one way or another about a product..but these are AMAZING! We were big Philips avent bottle fans during the infant stage, mainly bc they do not leak at all and were convenient to travel with..and these weighted straw conversions for the bottle are so great! The weighted straw works perfectly and does NOT leak like other weighted straw cups I’ve purchased for my baby. The handle is great, as well and fits snuggly. Not sure why we didn’t just invest in these from the beginning when we started the transition from bottle to straw cups. Super convenient since you already have the bottles - no need to spend extra money on different kinds of cups when you already have them. My daughter took to this straw immediately and they are now our go-to cup over any of the other straw cups we have.

Works enough
These are ok. Great for a transition from bottle to straw. We used it to transition from formula to whole milk. The only downside is it doesn’t have a great seal with the Phillips rings. My toddler is in the throwing stage and it immediately pops out and spills. Will also spill through the nipple.

Best purchase for my growing child!
Best purchase for my baby. Its easy for him to use, he can drink it in any position, and the handles make it easy for him to hold, and i didnt have to buy sippy cups for him since we aready use the avents bottles. 10/10 would buy again and will recommend to my mommy friends.

Good for plastic bottles and water
This is a great quality straw up but the functionality is not great. The straw is really hard to suck out of, which makes the flow tricky. Cleaning is really hard because the straw is so skinny. The lid leaks with a silicone sleeve on so if you have a child that throws things off the high chair this is not an ideal cup. The straw is best used with water and a plastic bottle that does not require a sleeve. The straw is too skinny for liquids other than water. We only have glass bottles so this is a no go for us.

Happy mom
Philip agent natural moms this is a must!!! Really great transitional piece for toddler! Toddler had no trouble transitioning and helped with independent feeding. The flow is similar to the nipple. If baby stops feeding it stops with and no over spill. It is easy to attach to nipple lid and easy to remove to clean. The set comes with a brush so helpful for cleaning. We do use it with the 9oz bottle as the straw is longer. Overall 10/10!
