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. :(

I have ordered numerous teas, potions, lotions and other remedies...BUT have never had a lack of product in an order that was sealed.  The tea bag wrapping in question was sealed without a tea bag inside.  I would have said something sooner, however...I only tried these when I had a sinus infection and the last 3 times I tried to use one...the sealed pouch was EMPTY.  BEWARE!

We live in an area that does not have a lot of stores that carry organic at reasonable prices. That said I found the product to be a good value and convenient not to have to sometimes wait for local stores to restock, if they even stocked.  Yes, some cans get dented in transit but it really was not a big problem for me. I hope the future delivery is the same or better.  It is unknown if the can lining is BPA free. I try to avoid it but until the manufactures get it out it's near impossible to buy canned goods that don't have BPA in the can lining. Pregnant women should avoid anything with BPA in it and if I had growing children I would also strive to avoid.
