Pros: Works great. I installed it into my macbook core duo 1.83 ghz. I replaced the default 512 mb of memory that the macbook(old version) came with. So far no problems, worked straight out of the box and installation took less than 10 mins. Now I can multitask like I want to!

Cons: None so far

Overall Review: I got a great deal. Apple way overcharges their memory. Unfortunately, I see that now the price has dropped even lower.

Pros: Very good product. Does what it's supposed to do. I connected my Yamaha PSR-292 to my macbook and it works great with garageband.

Cons: I wish it was cheaper, but as a product no problems.
