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.

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.

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.

Missing items.. but everything else was good
Initially, I was super excited to try this out with my baby. When the order arrived, I was ready to take everything out, wash it and use it immediately. The more I looked at the order I realized I was missing the 6 cleaners that said came with the order. They were no where to be found. That already bummed me out. I just tested out the size on a bottle, and they fit quite well with Philips Avent plastic bottles. Handles look good. They do not leak, which is really nice. We’ll see how baby likes it after they’re done drying.

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.

Great!
Got these for my son and I love them! They’re easy for him to use not too much liquid comes out at once. They’re light and I love that the bottom is weighted so even when he tips it up he’s still able to get the drink! They’re pretty easy to clean as well. Recommend to my mom friends!

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.
