PROBLEM: I bought it to my mom and she's been enjoying it. The battery last for couple of weeks, she has a very large area, but only 2 dogs so it's fine

SOLUTION: Good Review

PROBLEM: The description of the book sounded interesting. What I discovered was that it had a very poor plot. Only read to 60% then skipped ahead and saw nothing but pages and pages of descriptive writing. Nothing about a plot at all really. You might want to take notes as you keep reading, it's not a story. Read the last few pages, its pretty decent. Then skip ahead. It's no better for you. Sorry. But I am glad this one got cheap. That's why I've bought over 1000 books from Amazon.

SOLUTION: Bad review

PROBLEM: Do not spend money on this product. Although I have used the first of two cartridges, my printer does not recognize it as a new cartridge. It keeps telling me to replace the cartridge, even after replacing it. This is such an inferior product and no where near being worth what they're asking. Buyer beware.... You are better off paying more for one from Canon. Even though it's less expensive, you will save tons in gas by purchasing your cartridges directly from them.

SOLUTION:
Bad review
