This orange soda is clearly more healthful, and it tastes tangier, although somewhat less sweet, than other orange sodas.  The one big drawback for me was that this drink lacks caffeine.

Short and sweet.....The product itself is top notch and my two GSD's love it. However, the last shipment looked like it was packaged by a three year old and thus it arrived via UPS with a can lid popped open spilling its contents over the other dented cans. Another case arrived seperately which was properly packaged using air pillows and was fine. Don't get sloppy Amazon. It will cost you customers.
