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 personally enjoyed ever word of this particular work. Many other reviewers have gone into the plot, etc. so I will not do so here to any depth. This is one of those works of SiFi that will appeal to certain taste, while others may find it not to their liking. There is a great deal of politics (almost Pre WWI European) involved in the story line. As the story covers (all books included) over one thousand years, there are many, many characters to track and keep track of. This is indeed a series of short stories, all linked. I personally enjoy this sort of thing but can see where some might not. That being said, it, the book, can certainly be regarded as a classic in this particular genre and certainly should be read by any student of such. You certainly cannot fault the author's story telling ability and imagination. I enjoyed this one a lot and do highly recommend it.

Output: Positive


Input: Consider Input: Had to offset the praise handed down by so many people for Karourac's writings. Very overrated as a writer. This book is filled with the resemblance of substance, but has nothing in it. It is a contradiction of itself.


Output: Negative
