Q: I hate this printer! It is nothing but problems. Every single time I go to print even a single page, there is some sort of problem! The paper jams, I get timeout errors, the ink runs out too fast and I am unable to fill it with the refill kits. The thing has a mind of it's own and starts spewing out pages even when I'm not trying to print anything. It wouldn't be so bad if it didn't put trash on each page wasting my paper. It's a piece of junk! 1 Star is highly overrating this product!

A: Negative
****
Q: In a word- horrible. I am a HUGE fan of the first two. Watched the cartoons as a kid, and i really couldn't wait to see this movie. It was horrible. Rambling, incoherent, and unfocused. I missed Megan Fox every minute that pouty, big-lipped female was talking, and fell asleep after 20 minutes.

A: Negative

Q: Gifford is one of the top experts on Heinlein's works, and his "A Reader's Companion" is an exhaustively researched and well-thought-out compendium of nearly all of Heinlein's work.I say "nearly" only because the book misses a few Heinlein collections and such that have been published in the few years since Gifford's 2000 printing. [...]I've been collecting Heinlein works for years, even very obscure ones, and I still learned of new things from Gifford's book.

A:
Positive
