Input: Consider 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.

Output: Negative

Input: Consider Input: I purchased this for my husband to load a recertification course on and study. He also has music on it and is enjoying it very much. It was a great price, especially for this much memory. And Amazon's service was great as usual.

Output: Positive

Input: Consider Input: maybe they are clever enough to figure out why these actresses,directors, producers, etc. are still in circulation.This film is not only BORING BORING BORING but also an INSULT to everyone ... except perhaps the Far Eastern looking "actress" who gets to play the "friend" of the protagonist, and who fairly deliberately ruins what was supposed to be a one night-stand (one-night lay to be more precise) anyway, on the part of the slow, but dark-looking Italian HOD (hunk of the day, my abbreviation, he-he). Don't worry, a bearded, rugged looking American is going to fill the Italian's rubber shoes ... Sorry for italianizing and americanizing but there is more than enough of that going on in the film, at least on the DVD version.The film forgot to elaborate on the potential dangers of adult owls snatching kittens though, as it's a romantic, and not a realistic view of the world, and it was definitely not meant to be a horror flick. Then again, some of the scenes are pure horror.
Output: Negative
