Example Input: I ordered this because so many people were saying that it was sugar free. It's not. The first ingredient is "SUGAR". It's too much of a pain to return, so I'll keep it and drink it (because it's a pretty good K-cup hot chocolate). I will think twice about ordering it again though. I'd really like to get what I ordered.
Example Output: 4

Example Input: I don't write reviews at all but I'm just going to say that this is a very decent product to buy if you're not looking to spend hundreds of dollars on a mixer, phantom power supply, and pre-amp for XLR mic recording. Because guess what this little thing has it all in one all for a low price! Cop you one!
Example Output: 5

Example Input: I'm disturbed that these treats, as many reviewers state, are so "addictive." My dog, too, loves them but has now begun to shun her meals and will only eat these treats. In trying to make sense of her current state of anorexia, I recently became aware of the FDA advisory on Dec. 19, 2008 stating that one of the symptoms to be aware of in dogs eating chicken jerky treats made in China is "decreased appetite, although some may continue to consume the treats to the exclusion of other foods." So be very wary of the fact that dogs seem to go crazy over these treats. Although the Dogswell Company states clearly that their product is not contaminated, and that third party testers have confirmed this, do the owners of the company truly know what's happening in China behind the scenes? Or who might get paid off to test certain batches of jerky? I and my vet have been unable to come up with any other explanation for my dog's anorexia, except that it coincides with her increased interest (and now ONLY interest) in Happy Hips since I began treating her with them last spring. Thankfully, her kidney function is still fine, but if you research this on the web, many other dogs were not so lucky and died due to kidney failure. See this link to the FDA website suggesting caution to consumers in using chicken jerky products from China. Be informed! [...]
