Example Input: This DVD is one of my all time favorite musical DVDs. Miss Jackson proves why she is the highest paid singer in the industry. With a combination of costume changes, great choreography, Janet's greatest hits, and a sold out crowd at Madison Square Garden, the DVD makes for an excellent night of entertainment. I only regret that I was not able to see the concert in person here in my home town due to a cancelation of the concert;however, the DVD is definately a suitable substitute. I highly recommend this DVD to any fans of Janet, lovers of music, and owners of quality DVDs.
Example Output: Positive

Example Output: Positive

Example Input: I'm training my waist to lose inches. I used to always buy fajas which are very uncomfortable and takes alot of getting used to. I wear them most of the day and throughout the night. This one is more comfortable (as something squeezing u can be) and looks good under certain clothes. I like that the inside is a rubbery material that helps u sweat. It speeds up the weight loss process. I plan to buy the next size down soon because my waist has already shrank! I probably will buy the one with the straps next time because the strapless does kinda push ur back fat up and with certain clothes you can see it. All in all it's a great product and the most comfortable cincher I've ever bought.
