Example Input: Review: I bought this because it was a cheaper alternative to Mac's (ridiculously priced)$80 charger. At first it worked pretty good, but about a week or two after i got it it seems to not be working like it should. i think there is some kind of warranty, so i should try and exchange it...but sometimes when it is plugged into my computer it will charge for one second, then stop for one second, charge for one second, stop for one second, etc. It still manages to charge the computer, but im not sure if all this on\off stuff is necessarily good for my computer...

Example Input: Review: Please ignore the immature high-school student reviews and understand that this book is a masterpiece. Hardy analyzes the relationship between human desire and society's mores to an unprecendented degree. The characters are multi-faceted and very life-like. Hardly aptly avoids the mistake of creating mere carciatures of the pure woman, idealistic intellectual, and spoiled playboy. Moreover, his use of religious allusion is excellent although this may alienate the modern, secular reader. And perhaps this is the problem with some readers. Finally, Tess is an admirable and strong woman who had difficult circumstances. How many people would act as admirably in her circumstance? Not many! The reviewers that criticize her actions should realize this and that they ignore one of Hardy's key points: Don't be so judgemental! This is one of the best books I have read and believe me, I have read a lot of the "good" books.

Example Input: Review: this video has a lot of dances for learning but each dance has only 3 steps so dont expect so much from this teaching video. if you want more than 3 steps then buy videos exclusively for a particular dance. this video will just wet your appetite but will not fill your hunger. also, the background setting of this video is very dark as if you are inside a dark night club so you cannot see the footsteps of the teachers because both of them were wearing black pants that blend with the dark background, terrible! plus the teachers teach from the side of the camera and sometimes facing the camera. this is not the ideal way to teach dance in a video. the teachers should be back to the camera so you can follow their footwork. for the money they charge for this video is not worth it.
