Example input: I have bought several of the Vitality canned dog food products and have found them all to be of good quality. The product looks more like a stew than a processed meat and it smells better. My Labrador is finicky and she appreciates this product better than  most.
Example output: 5
Example explanation: The user really seem very satisfied with the product and gave good review worthy of 5 stars rating.
Q: Is that these are 60 calories per serving, however, in all honesty, I didn't make it through a full serving.  I was excited about these, they looked like a "grown up graham cracker".  First problem was the smell. They smelled like melted plastic, and something else I'd hesitate to even guess what it is, but it's bad. I bravely pulled out one small crisp, hoping that maybe it was the packaging that had the ... aroma. It was not. The crisp itself smells horrific. I figured there was no way it could taste as bad as it smelled. Second problem is that I was very, very wrong about that. They have a funky, chemical taste that just defies description. The aftertaste is sort of like a skunky/chewing on a plastic pen cap that went thru the wash/wet cardboard kinda taste. Seriously, it was awful.  I tasted these about 45 minutes ago, and after drinking an entire bottle of water AND brushing my teeth, I CAN STILL TASTE IT.  I'm glad these were an add-on, but they are still absolutely terrible. Their only redeeming quality is that they are cute. Not one single member of my family will actually eat them though, so this was definitely a waste of 3$. Had I known they would be this awful, I'd have just got a second bag of <a href="http://www.amazon.com/gp/product/B007POA158">Hi I'm Skinny Sticks, Sweet Onion Multigrain, 7-Ounce</a>. Only 30 cent more than these, but MILES better in taste.
