Example Input: The bed needs air refilling more often than I thought it would- every 3 days at the most. So much so that if I didn't pump it, the bed would all be like a water bed with "jelly-like" feeling. To lessen this effect I situated it in a corner of the room against the walls. Further more, what surprised me was the round water condensation on the bed sheet just underneath my (head) pillow in the morning. But what confuses me is that in the evening the bed feels cold (or the air inside feels cold).What I like about it though is that the pump works real fast in inflating- although it is loud for an evening activity.
Example Output: Negative

Example Input: This review refers to the new Special Edition DVD that has just been released.Both widescreen and full screen versions are included, but more importantly, the original Australian dialogue has finally been restored. The difference between that and the clunky, awkward American-dubbed audio most of us are familiar with is like night and day (and if you want to find out for yourself, both are included on the disc, so feel free to compare).Rounding out the package is a making-of featurette, several trailers, and a "pop-up video" style subtitles-option which presents various minutea about the film and its locations while you watch.

Positive
