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.

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 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.

Works good for baby’s
Fits perfect on the 4oz and 8oz avent glass bottles. Easy to clean, doesn’t leak out! My baby throws the bottle tips it upside down and it doesn’t leak. Works good for our 8 month old

Perfect
This is my third review ever and I’ve been on Amazon for as long as I can remember. Get these converter kits. My son has had issues with latching since day one, so we couldn’t use the Avent bottles. He’s gonna be a year already and we’ve been doing sippy cups for almost two months. All the cups are different; all the levels of force needed to sip are different. These are perfect. Not too easy that they spill or he chokes, and not so hard that he can’t get anything out. Now I can finally use these bottles!

Great for breast fed baby!!
Perfect for my breast fed baby who didn’t understand the concept of tilting the bottle up for milk!! The straw moves to the liquid so she can drink it in at and direction. Doesn’t leak either!!

Love it!
Absolutely love these! Fit perfectly on the glass bottles making it easy for the transition into a sippy cup! No leakage, easy to hold, & definitely worth the buy. Super nice not needing to buy extra cups/bottles! My little one had no problem using it for the first time either.

Great Idea but Thin Material Toddler Bit a hole Through Straw Nipple
I wanted to love this product because it converted our glass Avent milk bottles to a stray cup however less than 3months of use, and we found a hole in the straw nipple. It’s supposed to be food grade silicone and safe but toddlers teethe and I’m concerned that more can chew off the plastic and swallow. I wish we could get a replacement perhaps of thicker grade silicone. The straw is also very tiny and a bit difficult to wash and put on but it does work and the weighted piece is very smart. Overall the concept is great but the quality of material leaves much more desired. I had high hopes but given we are down a straw nipple and they don’t sell the nipples separately makes me worry about the safety of the items.
