Example Input: Currently, there are no wholes throughout the bed. But, for some reason when I wake up. The bed is already out of air. I only weigh 120lbs. I don't understand why it does that. Please save your money, when you start to have the same problem.
Example Output: Negative

Example Input: Great tunes dripping with latin up beat melodies and smooth syncopation. One track could have easily appeared in a 007 flick.Slick production and sound makes for great party music ; dancing or sitting ! "Oh yeah" will always turn an ear with or without the accompaning movie.......
Example Output: Positive

Example Input: While the flexability is nice this uses non standard triple a batteries which is uncommon for most vibrators. Size is actually a little small and no twisting inside, I would recommend this to ladies who like it small or first timers.
Example Output:
Negative
