## Description

desertcart.com : Sippy Cup Soft Spout Conversion Kit for Philips Avent Natural Baby Bottle, Bottle Handles and Weighted Straw （2 Pack） : Baby

Review: Perfect fit - Perfect converter for the Phillips avent bottles! Easy to clean and easy to set up. Have only had one spill so far where nipple came out of ring, otherwise pretty durable when dropped/thrown.
Review: Great for transitioning to sippy - Would give 4.5 stars if a could due to product inconsistency. I ordered this item twice. The first set I got look like the item pictured, the second looks slightly different (the straw part is longer). That being said, the items function the exact same. My 9 month old took to these immediately. Have not had any issues with leaking. Cleaning is pretty easy so long as you separate the nipple and straw. Plus each set comes with cleaning brushes so no need buy them separately. Overall happy with this product.

### ⭐⭐⭐⭐⭐ Awesome product
*by L***A on January 20, 2026*

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.
