Before buying I thought about because of the many positive reviews on other storage bars, if I do not perhaps you prefer a Kingston or Samsung to buy 8GB Kit. However, since these are a bit more expensive but then I have ventured to the Corsair.
Shipping ran through Amazon - The store was sent a letter shipment to a packing station and arrived without delay in stable packaging.
The installation in the MacBook running without a hitch. A Philips screwdriver PH 00 necessary - for Unibody Macbooks is only a very small precision screwdriver or - even better.
A Super installation instructions can be found here:

And now the most important: The memory runs great and flawlessly. My MB detect :) the full 8GB.
The only mini drawback: The memory module stick pretty firmly in the package.
But still - strong buy recommendation.
