[EX Q]: When used in conjunction with a new water filter i no longer have to replace my Brita when we change filters. Very easy and fast to get the water flowing. You can switch them out more then once.
[EX A]: Good Review

[EX Q]: My dog is a very picky eater, and will eat almost anything with no problems, but this food has been given to her about six times within the last 6 weeks or so. It's okay if you aren't feeding large amounts of each type every day (for example, half an average bag+1/2 per day). But not great since there are much cheaper, less expensive, healthier choices available for pets.
[EX A]: Good Review

[EX Q]: After about half of the book was read, I had to force myself to keep plowing on. The storyline seemed interesting but the writing style and character development left a lot to be desired. It's not even worth it if it's free.
[EX A]:
Bad review
