        My wife uses an older MacBook. After I upgraded to Mac OS X Lion things started to get sluggish. The beach-ball would be seen more frequently. After some analysis with vm_stat I was that it was paging quite a bit since she only had 2G of memory in the machine. Installed this 4G set and the difference is substantial.

              These RAMs are fit to iMac early 2008. They perform pretty well. Easy to install and acceptable price.

              My Mac run faster, I open Photoshop, Illustrator and Dreamweaver in the same time, and it takes only about 5 second to finish the jobs.

              I hope I can upgrade more but 4GB is enough for graphic design.

              I used this memory to upgrade my 2.8 / 800 INTEL iMAC. It took only 10 minutes to pull down my system, install this memory and restart. For you Mac Users out there running 10.5 or higher I tested this memory by deleting the same 4.3 gig file twice using Secure Empty Trash. Prior to replacing the memory this task took 11m38s after replacing the memory it took 4m18s. If you are looking for an easy upgrade for a 2 year old system this is the way to go. Under $50 you will be able to bring your system back to life with easy compatibility and installation. If i could have giving 6 stars i would for this product.

                                    My computer slowed significantly as I started using photography applications. This product was relatively cheap, easy to install, [...] My computer runs like a young puppy again with the added memory. My only complaint is that I purchased a total of 4GB and my computer is only registering 3GB. In the long run, it was not worth it to me to call/complain/return the product.

                                                I used 2 GB to upgrade my netbook and the other 2 GB for my wife's. What a huge differance, it is nearly as fast as my laptop now.
                                                Great price.
