“Despite their claims, this does not taste like Coke. It has a taste similar to it, but there's sort of an earthy taste that is off-putting. The other problem is the delivery system. Dissolving the tablet requires time. For plain water, that isn't a problem but you get a "flat" cola. But, if you want to use carbonated soda, it becomes a problem. None of the bottles or cans come in the right size, so the mixture is "off." When you do it, the carbonation starts to dissipate and, no matter how I tried it, even the carbonated soda was flat.”
“This tastes nothing like a cola with or without sparkling water and it was difficult to open and if your using a cup other than the specificiations listed on the package, you're hard put to get the right amount in your water.”
