Title: filter Review: I haven"t installed this filter yet. I can"t believe how big it is. The media comes preinstalled in the filer basket. The canister was dirty, but I don"t think it has been used. I would like to talk to someone before I set it up, although it seems pretty simple. Does this product review convey a negative or positive sentiment?

Title: If you only have time for one book, this is it. Review: Gregori introduces the topic well for beginners, but goes on to make a no-compromise argument that to be prepared for the worst is only common sense, and to not prepare is folly. Much more than an introduction, he then provides many resources to help the reader prepare. I'm buying this book for all my skeptical friends. If they're not interested after this, they'd better not come calling in January, 2000. Does this product review convey a negative or positive sentiment?

Title: Thin but good for layering. Review: The orange is not as bright as I thought it would be. Not bad. Good enough for my jobsite.The material is thinner than I thought it would be, but it's alright for layering, and feels nicer to wear than a safety vest.
