Example Input: This camera was not very user-friendly at all. The first time I went to use it the shutter button got stuck. We could hear and see things flash on screen, but no picture. After spending almost a half hour trying everything, we finally gave up because this is too big of a headache for me. Now I'm just going to get a point-and-shoot type without all the complicated settings. My advice, do what everyone else does.
Example Output: Bad review

Example Input: I don't know what to write here, this product didn't work at all for me. It was a complete waste of time and money. I tried it on one eye first, the light did not affect my eyeglass frame or any other part of my body whatsoever. To conclude just dont buy. I will probably never be able to find something else that works. Save your money - there are plenty others out there. I wouldn't suggest giving this little cheap thing even 1 star but you have to.
Example Output: Bad review

Example Input: If you're interested in an alternate version of Sherlock Holmes, then this is the right book for you. A number of great stories are featured here. The inclusion in this collection were definitely more interesting than the short stories. Many classic Holmes characters came to life through these stories, and while they weren't exactly what I remember, I'm glad that Conan Doyle helped put some new pieces together. Well written story, but not as good as a typical story would have been. As always, Mr. Cumberbatch can act.
