Pros: What can I say? The memory performs flawlessly in my 2.8 GHz Core2Duo 15" MacBook Pro. Saying that makes me sound like a prick but I have talked to people who are nervous to put hardware in their Macs that hasn't been officially sanctioned by Apple. Rest easy, this RAM will treat you well.

Cons: Sadly installing this extra memory boosted only my system's performance. After reading some of the other reviews here I expected every aspect of my life to drastically improve. Unfortunately I'm still just mediocre in bed and my musculature wasn't transformed from that of a person who spends hours in front of a computer to that of one who spends hours in a gym.

Overall Review: I prefer cash in my pocket to Crucial's RAM in my socket.

Pros: Quality built cable that fills its purpose. Solid ends and fit the drive snuggly.

Cons: Sata end might be just a hair wide externally as the power and data cable had some slight interference when I plugged them both then. It could be the data cable that is a hair wide. They both fit but it was tight.
