Came with no rubber plug in the breather meaning that everytime it was used water ended up all over the little one’s face! Not impressed with the product.

If you're looking for a decent, leak proof bottle for yourself or your children you've found it! My 4 year old uses this for school and even though he's dropped it multiple times on the pavement it's still going strong! I love that it'd a metal bottle and the designs are super cute. This is our 3rd bottle from ion8 and we will never use other brands.
