3-in-1 Weighted Straw Sippy Cup Conversion Kit for Comotomo Bottles | Versatile, Leak-Proof - Easy-to-Use Solution for Babies and Toddlers | Compatible with 5oz & 8oz Bottle (Green)

It’s been a week we have been using this straw cup kit. I am now comfortable leaving a review. First, the product it well made, the color matches perfectly, and it was easy to assemble. It comes with a manual with a QR code to access it online, but we did not really need it. There are pros and cons that we found, and also a couple of tips.Pros:Well made and fits the bottle well, both 5-oz and 8-oz sizes.The color matches exactly.Does not leak.Works as described.The weighted straw is genius! It really helps to drink the milk/water from any position because our baby is not strong enough yet to lift and hold the bottle up when she is in the upright position. The straw allows her to drain the bottle from any position.Cons:The straw is a little hard to suck from (yes, I tried), but I guess this is the idea. So what we did in the beginning, we pressed on the bottom of the bottle to make it easier to suck the milk out, and the baby got it. Now she drinks from it happily.The manual says the straw is sized for 8-oz bottle. This is not precisely correct. Don’t cut the straw! We use the original length with both 5-oz and 8-oz, and it works perfectly. Just make sure the 5-oz bottle is more than half full in the beginning.Finally, but this is really minor. The liquid pools in the depression around the straw when baby drinks. It comes from whatever leaks out of her mouth. Not a biggie, and I don’t think it can be avoided.Overall, our impression is very positive so far, and we are happy to be able to keep using our favorite baby bottles.TAG:Pros and cons but a great product overall

Excellent product. My baby loves it and is able to use it independently at 11 month age. A little difficult to clean, but you can just blow at one end to get any food particles out that gets stuck in it.

Love that this is available and I choose it to allow my LO to feed herself in the car.However, I didn't get the leak proof gasket and as such it leaks out the milk once the bottle is tilted.

My 18 month old loves these and we are glad to re-use his ComoTomo bottles. Fits great and works as described.

We loved this lid for the first month we had it. Loved that I could reuse my bottles, loved that 6 mo daughter knew how to use it right away, not too hard to clean if you have a little brush for the straw. BUT about a month in the little part that covers the air hole in the cap wouldn’t stay in place. If baby tipped the cup liquid would pour out. Also my daughter discovered that if she squeezes the silicone bottle base, liquid comes spitting out the straw. She is drenched, the floor and high chair are drenched.

This conversion kit is exactly as described. It fit our comotomo bottles just right and has allowed us to extend their use as a straw cup. The biggest positives are the weighted straw that keeps the tubing in liquid and the spout cover for travel. The only downfall is that the straw leaks if the bottle is squeezed but that is right in line with what the bottles do when used as bottles.

I got these to transition from my babies bottle to sippy cups but they are leaking terribly! I wanted to love them bc he can drink easier from them and they have a lid that covers the straw but I don't see the point of the rotating lid when the bottle leals lime CRAZY from threads where it twists on.

This is such an amazing add-on for our favorite bottles. The weighted straw is just long enough and weight is small enough to enable baby to remove all milk from the bottle. I pump breastmilk and I was annoyed at other bottles wasting 0.5 oz because the straw is just not right.The mouthpiece is wide, easy to suck up the liquid, so it was easy for my daughter to get used to it, and easy for me to clean. The top closes reliably, it never spilled for us. She chew through the straw in one year, I think that counts as quite durable given that I use this every day.
