Great cup
Yes the lid will break if your child drops it while itâs open. I usually just take it off while my son uses the cup and then use the lid when the milk is kept in the fridge or when I need to put his cup in his backpack. For someone who does not like to use plastic this cup works great! The straw has a stopper to prevent liquid to come out but my son has never had an issue sucking out of it. It cleans easy so no mold will grow in any small spaces. I love these cups!

Nice bottle
I got this bottle to give smoothies to my 1 yr old in. He really likes it! Itâs light weight enough for him to carry around and easy enough for smoothies to go through. He even likes it for water. A couple of things I didnât like was that it came with instructions to cut the straw at a slant on the bottom. Not a big deal. And the straw is not one piece. You have to stick it inside on the bottom. If you donât do it well enough it falls out and bb can not drink. That being said, it was the best option I found for a non-plastic baby smoothie bottle. Love the green color.

Not impressed
I had some really high hopes for this based on other reviews and for the price I had some high expectations. It feels really cheap, the lid is plastic the straw is flimsy silicone as well and the lid pops off easily. I don’t really recommend this for babies.

Love it!
This is a GREAT cup! Non toxic, and a slow pace straw. Im so happy with it. It works so well for our 14m old!

Nice stainless option for toddler or kid smoothies.
We wanted this cup for toddler use at the table for milk and water. This cup has a large diameter straw which was far too large for our needs but would be ideal for a thick smoothie. The parts are easy to clean and the straw part being on the disk makes a seal with no separate part to clean… a real plus. Given the size and heft of the cup, I wouldn’t recommend it for children under two.

Love all things Mason Bottle, have tried every product
Just like the title states, I love everything Mason Bottle has made. Used the nipples all the way up to the straw with my son. My daughter is on the way and the products are so good that I only am replacing the nipples. Love the silicone bottle jackets, love this stainless steal bottle. Everything from them has been amazing quality.

Breaks easily
I love the bottle bc itâs super easy to clean. Can use the straw or sippy. However within a few days the lid was shattered and broke off. I got a new one and the same thing happened within a day. Not good design.

Passed the “baby drop” test.
He loves it but drops it often.. it’s dented but still very much functional. I got a second one to have 2 on hand for long drives.
