[EX Q]: 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!
[EX A]: Negative

[EX Q]: Sorry! The sweet and sour chicken dinner should be called sweet and sour water chestnut dinner. I found almost no chicken, other than tiny pieces, and LOTS of water chestnuts, which I don't like. Even if there was more chicken, the flavor leads a lot to be desired. This is one dinner that will not find itself on my grocery list. I remain, totally disappointed, Shirley
[EX A]: Negative
