Pros: None.

Cons: -Failed after a couple of uses. -The unit is too tall, which means I can't shift gears easily with the charger plugged in.

Pros: The stick that works does the job

Cons: One of the sticks was DOA.

Overall Review: My MB beeped continuously when I installed the memory and I eventually figured out one of the sticks was dead. I've read somewhere that this was due to the static in the packing peanuts. Whatever the case, I did not realize there were so many of one stick failures. I'm simply adding to the statistic and hoping the next batch I order works.
