Great for beginners!
No leakage, fits perfectly with the Phillips Avent bottle. Easy transition from bottle to sippy cup.

Awesome product
I love this it’s SUPER easy to assemble, easy to clean. I’m not yet sure of how durable the nipple is since I just started using it today but my 6 (7 tomorrow 😊)month old has two bottom teeth and has yet to bite a hole into it. It does seem durable and sturdy though. It doesn’t leak which is awesome since he just leaves his bottles thrown all over the bed 😂 I highly recommend the price is awesome. Everything about this little kit is great. And it’s easy to use for him. He is able to lay on his back, on his tummy, on his sides, sit up and still be able to drink his milk.

Slow flow
This fits well on the Phillips avent bottle both glass & plastic. It functions well works as it should with no noticeable leakage. However I echo another reviewers note that the straw is very narrow. If your baby is already used to straws such as the honey bead cup, the straw gets clogged quickly and doesn’t have a quick flow. We used the Nuk straw cup instead and it was much better.

Works great
These are great! My child absolutely loves them. Great for 8 oz bottles, my son did not like the handles but holds his bottle fine without them so it works however they do have a slight leak in the top when warming up but was minimal so I didn’t mind

Great for transitioning to straw
These were great for repurposing my bottles without having to buy new straw cups. Great for transitioning little one to a straw.

Works as expected
Overall I do like this product and would buy more. I deeply dislike the handles included as they make the top loose if it’s thrown enough times. I both do and don’t like that the straw is in 4 pieces, if it were more like my Dr. Browns straws then it would only be two and much easier to wash, but with the four pieces I’m not able to put it all in the dishwasher. I personally take the straw fully apart for washing, I hand wash the tubing and all of the other pieces (not including the travel cases) go in the dishwasher on the top rack, the tubing is just too thin to safely put in through the dishwasher it falls right through my utensils caddy. I love the weight for these straws since it’s plastic it’s much heavier than the weight on the Dr. Browns straw and it will actually stay at the bottom of my small 4oz cups.

Love it! Doesn’t spill and works great!
The best product I’ve ever bought!! total lifesaver and easy for transitioning to a sippy cup!! fits perfectly on my Phillips advent glass 8 ounce bottles as well as the Phillips advent 4 ounce glass bottles. The weighted straw makes it easy for drinking on different angles without getting air. Does not spill without having suction to the nipple of the bottle! 10/10 love it!

Kit de Conversión con Popote para Biberón Philips Avent Natural
Compré este kit de conversión para biberones Philips Avent Natural y ha sido una excelente compra. Es perfecto para la transición del biberón al vaso con popote, ya que facilita que el bebé aprenda a beber de forma independiente. La boquilla es suave, no lastima las encías y las asas ayudan mucho al agarre, lo que le da mayor control al bebé. El popote con peso funciona muy bien porque permite beber desde cualquier ángulo sin tener que inclinar el biberón, evitando derrames y frustración. Me gustó que el paquete incluya 4 piezas, ideal para tener repuestos o usar varios biberones al mismo tiempo. El material se siente resistente y seguro, y además incluye cepillos para limpiar el popote fácilmente, algo muy importante para la higiene. En general, es un producto práctico, funcional y compatible, ideal si ya usas biberones Philips Avent. Muy recomendable para bebés que están dejando el biberón tradicional.

Leaks and doesn't fit as advertised
For the price I am very disappointed. The materials are of good quality, but the product doesn't fit or work for the Philips Avent nautral 9oz bottles as advertised. The straw is too long for the 9oz bottle and therefore doesn't work properly. The mouth part is also too long for a little one's mouth and leaks. The handles do not fit on the bottle at all. I would give 0 stars if I could. Absolutely awful. Don't waste your money.

Me llegó incompleto
Buen producto. Pero estoy un poco molesta porque me llegó incompleto. Solo venía lo de dos boquillas y la descripción dice que son 4. Aparte, al principio de usarla todo bien, pero después empezó a regar. No entiendo que pasó
