[EX Q]: I decided to try this formula for my baby since he started being very gassy. However, this formula made him more gassy...the formula is very thick and produces a lot of bubbles that gets fed to the baby. I tried to make the formula with anticipation to let the bubbles disolve but that didn't work.
[EX A]: Negative

[EX Q]: Makes great coffee for about 4 months. Cheaply made product. All pipes inside are cheap plastic. Even a $25 Mr Coffee has copper water pipes in it to carry the 190 degree water but not Keurig....all plastic water lines. Heat plugs the lines up in 3 to 4 months. Piece of cheap junk made to look pretty. Save your money
[EX A]: Negative

[EX Q]: I buy jerky all the time, always willing to try something new. I've even made my own at home. I agree with the review that called these salt sticks, they are way too salty for my taste. Also, being a jerky eater for 40+ years, I eat it because i like the toughness and chewiness of jerk. But the tube I got was nearly un-chewable. I have bit into some hard jerky in my time, but jeez louise, these were literally like chewing leather, many of the strips would not yield to my super powered bite.
[EX A]:
Negative
