I purchased a “generic” lemon lime soda called Diet Crisp Zero. I must say I was impressed. I love Diet Sprite, its crisp, refreshing and has just enough zing to keep you coming back for more. Now to let you know I really do compare various drinks to each other in specific categories. I will drink 7-Up if there is no Sprite around. I don’t enjoy 7-UP nearly as much due to what I call a dirty flavor, there is always a strange aftertaste to it. Now this specific knock off is REALLY good. It has all the zing that Diet Sprite has and it keeps it’s carbonation without going flat after being open for two hours. I recommend Diet Crisp Zero it is distributed by Save-A-Lot out of Earth City Mo.
