[Q]: 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!
[A]: Positive


[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!
[A]: Negative


[Q]: My boyfriend's cat has been eating this food for six years. When I switched my cat over to it, she developed a UTI and has been urinating all over the house. She also gained a ton of weight. Other reviews I have found online show that cat owners have had similar problems with their cats getting sick from eating this food. PLEASE use caution! This could make your cat ill. If your cat does eat this food, always keep an eye on him or her. I always thought male cats were more prone to UTIs and yet my female cat was sick. It cost me over $300 in vet bills from feeding her this food!
[A]:
Negative
