We play a card game that requires holding several cards. These card holders are a huge help. I really like having multiple colors.

Positive

Ex Input:
The plot develops nicely then ends abruptly with an unsatisfying ending. It seems to the reader as if the author had reached her contractual page limit and slapped an ending onto the book. A superhuman villian was terminated too easily. The method of capture was not adequately developed. Several promising themes were not followed up by the author, especially the entriquing possibility that through genetic testing Gault's uncle may have been his father or the reason for the military being interested in the investigation. The author took one of the least interesting possibilites and handled it in a below average formulaic manner

Ex Output:
Negative

Ex Input:
The description doesn't address the compatabilty issue with your computer. In my case, I purchased two, and had to return them both, since neither was recognized by my computer. Although the seller took them back for full credit, it's still a hassle, and a disappointment that it didn't do what was hoped it would. The rating doesn't necessarly rate the product, since it couldn't be rated because it was not compatable, it's more towards the lack of documentation regarding compatability.

Ex Output:
Negative
