Of the 12 cans shipped 11 of them had very, very serious dents in them. I'm not talking dings, I talking serious dents. So dented that I truly thought of throwing them away. My husband stopped me though because at $5 a can he felt that it was too wasteful. In my local grocery store, items this dented are put into a reduced price bin, because they usually don't move otherwise.<a href="http://www.amazon.com/gp/product/B002C4HZ00">Cento San Marzano Certified Tomatoes, 28-Ounce Cans (Pack of 12)</a>

These are great little snack packs - flavorful chips and fairly low fat and low cal.

This product label says that it is "the perfect balance between juice and carbonation", but I think the maunfacturer still needs to reduce the carbonation further. Also, I tried a couple of other flavors beside this kiwi/berry, and they are all mostly apple, grape, and acerola with a hint of other things. This particular item is called "Kiwi Berry", but there is NO kiwi fruit even listed on the ingredient panel. It is true that no corn syrup has been added, but there are still high sugars. For only 8.3 ounces of liquid, we are drinking 135 empty calories;however, this is a high level of vitamin C. Also, children will probably like these really sweet flavors, so this could be an alternative to offer the little ones.
