You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.

Example Input: I bought these when they were on a Gold Box deal...thinking that it would be a nice inexpensive toss in for a month of lunches...and then I'd never buy them again.  Not so...  They're actually really tasty!  Exceptionally crunchy!  And the flavor is similar to kettle cooked chips.  Definitely going on subscribe and save for a while.  I don't think they're any more salty than standard potato chips...but they're by no means "low salt."
Example Output: Positive

Example Input: I have ordered Breakfast Blend over the last three years.  The last order I received through Amazon was just awful! Bitter, burnt, undrinkable.....what are they doing to my once favorite coffee??
Example Output: Negative

Example Input: We fed Canidae to our two dogs for almost 5 years--they always ate it eagerly, never had stomach upset, and got raves from the vet for their muscle, weight, and coats.  It *was* a 5-star food.  But last summer we opened a fresh bag of kibble (same exact packaging bought from our usual store) and immediately noticed it was much lighter in color than previous bags, but we fed it anyway. Within a day our Aussie, who has a bulletproof stomach with absolutely no digestive issues, began to have horrible gas, softer stools, and really loud, liquidy gurgling noises in his abdomen.  We continued to feed the entire bag, thinking that he'd adjust to it eventually because our other dog was fine.  Well, our Aussie never did adjust to it; he spent a month having those symptoms, and we dreaded mealtimes because of the stench and sounds he'd create.  The kibble in the next bag we bought was the old normal shade of brown, and our Aussie's stomach noises, soft stools, and awful gas went away practically overnight. But by then I was hearing and reading that Canidae had developed a new formula that was making dogs sick. The stories about people whose dogs got *far* sicker than ours, and the dodgy responses that those long-time customers got from Canidae when they called to complain about the unannounced change, made us decide it was time for a new dog food.  We went with Healthwise, a premium kibble made by the same company that makes Innova, California Natural, and Evo.  It's not worth it to continue to be loyal to Canidae and to risk our dogs perhaps getting as sick as many others have.  Read Canidae's new formula horror stories at consumeraffairs.com.
