Pros: Excellent product even if overpriced. I have built hundreds of servers using 3Ware RAID cards with BBU attachments and you would have to be an idiot to install one wrong and burn up a card. In fact I don't know how you could do it. It is impossible to plug the BBU cable in wrong because it is keyed and that is the only attachment to the RAID card.

Cons: No cons

Overall Review: Buy it, install it, forget it

Pros: I have bought nearly 100 of these sticks from NewEgg and never a problem. I build custom Supermicro servers for clients and these are the sticks that run in anything (dual rank) and run cooler than most.

Cons: Wish they were 50% cheaper.
