I've tried a few different flavors of Switch and this is my least favorite. (My favorite is the cherry.) Unfortunately because I didn't enjoy this flavor I didn't find it as refreshing as the others.  I quickly handed it over to my son who does like kiwi berry flavors and he did like it a lot. Of course, since it contains enough vitamin C for a whole day, I felt just fine giving it to my child, too. No preservatives, no added sugar. I like the carbonated soda product a lot, just not this flavor.  However, the biggest flaw with this product is that it's too expensive in my opinion for the little cans you get. Rounds out to about $1 per can. Less than you pay often with a vending machine but twice what you pay for a flavored water or vitamin C juice pouch when you buy them in larger quantity. Not worth it. :(

Delivered by UPS, this product is just about perfect.  It does not have a disagreeable smell and the dogs love it.  It is much less expensive than prescription dogfood and our dogs are thriving on it.  You can even see an occasional pea and/or carrot. No grain to worry about.
