Review on CT2K4G3S1339M - Crucial 8GB Kit (2x4GB) DDR3 1333 MHz CL9 Memory for Mac, Enhanced SEO by Don Acevedo

I have a Late 2011 Macbook Pro 13 with Yosemite. Before purchasing this RAM, I checked my activity monitor and found that I'm using 3.8-3.9 of my 4GB of RAM all the time. Hard to lag behind. I received the package 2 days later and installed 8GB in about 10 minutes. Amazing results! I don't watch all my icons jumping around waiting for them to open. I STRONGLY RECOMMEND upgrading to 8GB. It's just day and night.
