5 out of 5 eggsWorks great!

Pros: Low cost, compared to $400 Apple was charging me for 2x4GB sims.

Cons: None so far

Other Thoughts: Make sure you buy the correct memory. I went on Apple's web site and selected my build (early 2011 MBP 15") and got the specs on the memory. Saw the price at the Apple store and checked Newegg. Installed memory per Apple's instructions, works fine (reads 8GB memory).

1 out of 5 eggsDOA.

Pros: Bad right out of the box. Not worth jumping through RMA hoops. Just lost $20.

Cons: DOA. Spend the extra $1 or 2 and get something that will work when you receive it.

1 out of 5 eggsIncompatible

Pros: Cheap, Probably works fine for newer MacBook Pros.

Cons: Is not compatible with the non unibody MacBook Pro.

Other Thoughts: Saying that this is "For Apple MacBook, MacBook Pro & iMac" implies that they all use the same ram. This is very misleading and obviously not the case. They should put which specific models are actually compatible.

Manufacturer Response:

We work very closely with Apple to ensure that our products are 100% compatible. Can you please contact us and let us know what specific problem you have so that we can look into this.
