We love this bottle. I have older version but this is better. The old one leaked few times. This one doesn't and it has sturdier handles. It is also easier to put on and take off dust cap. My toddler dropped bottle on the floor way to many times and it didn't crack. I never used nipple since my daughter is almost 2. She doesn't like sippy spout for her milk but for water she will use it. I think she got used to old one which fit this bottle too. Great quality and unique product. It is very hard to find something similar made of glass and not plastic. I highly recommend it.
