Example Input: I just wanted a simple, good looking case with the sleep function, and that's what i got to be quite honest. This could have been a great cover had it been made for the new ipad 3 as advertised. Instead, the sleep/wake function doesn't work when you close the cover. Also, even though I went in and out of this case several times, there is a chemical smell. Not sure if it's from manufacturing or shipping. Will do some touch-up work, but overall the picture looks great.
Example Output: Bad review
