Best conversion to toddler cups
This is a favorite product of mine! Love that it is compatible with the Avent bottle and is perfect size for baby or toddler use! It holds secure on the ring and passes 100% no leak test!

Overall, good product
We love these straw cups. We were able to easily use these pieces on our existing avent bottles when we were ready to switch to the weight straw cups from bottles. I love the weighted straw cups because when our daughter was learning to suck from the straw, she was able to lean the cup back like her bottle and still be able to get milk out. The familiarity of being able to lean the cup back allowed her to figure out how to drink out of a straw without needing to figure out at the same time that we don’t tip cups back when we are drinking from a regular straw. Having the handles was really nice, and I like that the straw was soft and flexible. My daughter did, unfortunately, start walking around carrying the cup in her mouth by the straw which did end up damaging the straw resulting in us needing to buy a replacement. The only negative thing I have to say about this product is that it is not leak proof. Most of the time it doesn’t leak, but sometimes there is a suction that makes the milk go up the straw resulting in that leaking out, but if you take the lid off and put it back on, then the suction disappears. Even though that does suck about the straws, I would buy this product again.

Fits Philip avent natural bottles perfectly.
These fit our Philip avent bottles perfectly and also the tall nuk sippy cups as well. I really like, they don’t feel cheap at all. The only thing I don’t like, is the milk comes up the straw and will “drip” out the top. BUT I have other bottles for my daughter with straws that do this as well. You just have to under the lid and the milk will go right back down.

Lifesaver for transitioning from bottles — LOVE
This little kit made the bottle-to-sippy transition so much easier. Snaps right onto our Philips Avent bottles, and the straw works beautifully — no leaks, easy to clean, and baby figured it out quickly. It’s one of those simple products that just works exactly how you want it to. I only wish I bought it sooner! If your toddler is resisting the switch, give this a try — it might just be your game-changer too.

Recommend for ready babies!
He’s not ready yet for this as it does come out pretty fast. An he don’t understand concept yet. But i do recommend it if your baby is ready. Even the spouts!

Longevity is questionable
I’ve been using these for over 8 months and I like these straw attachments. I’ve ordered twice since we lost a straw for one and I figured more is better than not enough. I really like that they come with the tiny brushes for cleaning. Without them I don’t know if I’d be able to find any small enough. The downside is after using them for so long sometimes the straws and weights are just slipping out of each other. My baby is over 14 months old and we’ve been using these since 6 months. He gets milk 3 times a day with these attachments. It’s becoming more frequent that they are coming apart and it’s annoying. I wash them daily and maw sure they’re fully dry by putting all the pieces in the bottle dryer. If I wasn’t having this issue I’d say 5 stars but because of this and how it seems like there’s no rhyme or reason I bumped it down.

Great conversion kit idea, not sure functionality
I’m not sure if it’s just my baby or what the deal is but he loves to drink from straw cups, but either doesn’t like this or doesn’t know how to drink from it yet. I tested it and it seems to work fine, but he much prefers his dr browns straw cup instead. Bummer. Good quality and value, though. It fits great on our Phillips Avent Natural bottles. They’re a little finicky with cleaning and re-assembling.

Transitioning Bottle Straws
Love these straws, they helped with the transition from a bottle to a sippy cup. They are not leak proof but still a great option for picky little ones

Straw adapters
Perfect fit and works as intended but drips if the cup is tilted, so as for infants its not that practical if not supervised

Bad one
Head does not sit properly on bottle. Slips off when pulled or opens from one side even if my baby just drops it. Leaks too much and not practical. The tube is so thin that it feels about to snip when cleaning.

Defective
The seller gave me a defective product. One of the item is broken. There was no stopper . I requested a refund but they have asked me to send it in my own expense. Upsetting.
