Bought these for a birthday and they were perfect--all arrived uncracked and wrapped really well. Super cute and perfect for 4 year olds.

Ex Input:
This product is good. However, I feel the carbonation is a little more emphasised over the fruity flavor. Unless of course carbonation is really wanted. I didn't find the juice flavour as good as Juicy Juice. And the cost is ~50% more per ounce for Switch vs. Juicy Juice for my region. I would say that for everyone who is interested in this product... let your taste buds be your guide.

Ex Input:
I was hoping for a health substitute for white flour brownies. It's OK, but not what I would serve to company. I substitute canola oil for the butter or margarine and that may have been the problem. Of course, I wound up eating them all anyway.
