[Q]: For $30 you cannot make any sense out of these CDs. Their supposed help section was obviously setup for their own benefit.
[A]: Bad review

[Q]: At first listen, I was not at all impressed. Although it's a catchy beat, the lyrics are cliche and some of them pretty inappropriate. But then another album comes along and my opinion changes. And that's what this is. Not nearly as impressive in production quality but still better than most music out there, and that's why it earns its keeps. Good job, Linkin Park!Update:Now that I've had more listens though, I'm impressed with it.
[A]: Bad review

[Q]: This product does well to eliminate some of the odor and is supposed to help with cat urine stains in areas that cannot be treated. However, I must say that it doesn't completely get rid for this problem. We use enzyme cleaner on carpet stains. Also, it seems to cause our cats scratching more when they are sick. On a positive note, this litter clumps up fine even when there are many "extras" - so no dust mess left behind.
