We first had Stonewall Waffle Mix when we received it in a gift basket about a year and half ago. We have been using it ever since. The flavor of the waffles are absolutely out of this world. We won't ever go back to Bisquick for our waffles!
Positive

I bought my mberry pack from mberry.us online hoping to use it to curb my sweet tooth. I followed the directions to the letter, allowing the tablet to dissolve completely on my tongue. I then tried balsalmic vinegar - nothing happened to the taste at all except that my tongue burned a little. So I tried hot sauce - nothing happened again except that my tongue burned a lot. Then I tried regular vinegar - nothing happened again. I even tried taking a second tablet, but it still did nothing but slightly burn my tongue. HUGE waste of money. Super disappointing. DOES NOT WORK!
Negative

As a long time tea drinker, was happy to come across this iced tea mix. It serves as my sports drink while exercising or golfing. I find this iced tea very refreshing. I really like the flavor and especially the low sugar content. The plain green is my favorite followed by the raspberry. The blueberry is good too; it's unsweetened, so I add half a packet of Truvia.
