Did it myself and it was very easy, just followed the video from OWC. Just make sure you discharge the power from the MacBook by taking out the battery and holding the power button down for a few seconds, you don't to damage yourself or the precious MacBook!! And when you put the new RAM in don't be afraid to put some pressure on the sticks to make sure that they are all the way in. Then when you start the computer again just make sure that OS X recognizes the new hardware in the system profiler.
