[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]: This 24-pack lasted about a month, and I sampled all of the flavors but only got to eat the barbecue flavor once, as it is my wife's and my favorite. So, I reordered just the barbecue. Great snack for 100 calories. I've purchased the reduced fat Pringles 100-calorie individual packs before, and you get a lot more chips in a Popchips bag than from Pringles.
[EX A]: Positive

[EX Q]: This is great pancake and waffle batter that was recommended by Amazon so I bought it and have been very satisfied with my purchase.  It makes the best waffles every time I have used it and that being said I am sold on this product.  I will be ordering more as we really like how easy it is to make.  I would highly recommend that everyone try this who likes pancakes and waffles it is delicious and very economical.
