Review: Pros and cons , but a great product overall - 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
Review: Exactly as Advertised - 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.

### ⭐⭐⭐⭐ Decent product
*by M***E on January 22, 2026*

A great product and very useful!! We love our comotomo bottles and this made it even more valuable and useful. It makes the transition from bottle drinking to straw drinking easier. The only reason for giving 4 stars is because it has more parts that needs to be washed. In general I try to buy bottles with least parts so that its easier to clean.
