[EX Q]: I tried this carrot juice for the first time today and regret buying it.  I took my first sip and actually wondered if someone had put pickle juice in the jar.  It was awful.  I've had several carrot juices and never had any as sour as this.  It is difficult to fathom how this product is still produced.  It has lemon juice in it, but apparently far far too much.  If you enjoy pickle juice with your carrot juice, you will love this product.  I don't.
[EX A]: Negative

[EX Q]: Great selection of chips & very fresh. If you are are looking for a healthy alternative to fried potato chips & don't like the fake taste of baked, these are just the most amazing chips you can eat. I bought 2 cases & every time I'm at Target or our Super Box Store I make sure to pick them up!!
[EX A]: Positive

[EX Q]: My dog will happily eat Sorel boots, pens, old work gloves, and any paper product but chewed on one of these treats for a couple seconds and just left it sitting on the floor.  This is the first time I've ever given her something to eat that she didn't basically inhale.  How do you eff up making a dog treat?
[EX A]:
Negative
