Love it!

This was our first time using a glass bottle and love how we can use our own Mason jars, makes it very affordable. Baby took the bottle no problem. Love this sustainable and healthy option. Wish I knew about this with my previous babies.

Love these

I've always had trouble getting my babies to take a bottle. I'm nursing my 3rd baby now and it's the first time I've been able to give my child a bottle at 3 months old. So glad I tried these bottles. I adore being able to freeze milk in the same jar baby is going to drink from and that baby is drinking from glass and not plastic.

Very pleased with the Mason bottle purchase. Baby girl takes the bottles with ease and no issues. So very delighted to be away from plastic. This is a great product

Like the idea but still not right

I had to buy multiple nipples for the different flows because there wasn’t a way to select a different nipple flow with the original set up. It was extremely difficult to find an 8oz mason jar that fit the nipples. On top of all of that, my daughter can easily pull the nipples out of the sealed mason jar & then milk/water just goes everywhere. I loved the general idea of this but sadly will be returning this product & our hunt for a bottle continues.
