Rating: 4/5 nice to have extra memory, but don't notice much diff February 4, 2016 Well ... I swaped-out 8GB of MacBook Pro RAM for these 12GB DIMMs. EASY to do; NO problem at all. And ... I guess it IS nice to have more memory ... but frankly, I don't really notice much (any!) performance difference. But in fairness - I DO have LOTS of apps/files open and in constant use, all the time. At the LEAST, two huge Excel spreadsheets-with-graphs, two LARGE FileMaker-Pro databases, a Firefox browser with multiple often-large tabs, an elderly email client (Eudora , oldie but I have 20+ years of archives in it!) ... plus numerous other apps and files that I also use randomly. With ALL of them open and in use!

Rating: 5/5 Good price, Good product, quick service April 9, 2015 Title says it all. The chips arrived on time, slipped right into my MacBook Pro. I was a little confused about one issue, and their tech support person helped me out clearly and cordially. Recommended.

Rating: 5/5 The product works great and it arrived on time. February 6, 2015 I wanted to upgrade my wife's RAM and HD on her laptop for christmas. OWC made it very easy to find the right models and they shipped them to in a very timely manner. My wife's computer runs much faster now with the upgrade to 12 gb from 4 gb. I have nothing but good things to say.

Rating: 5/5 Very good buy! October 23, 2014 I was thinking of upping my 4GB RAM to +10GB for quite a while already. Since I am using several Adobe products such as Photoshop and Lightroom, as well as KeyShot and other computer graphics programs a lot now, it was finally time. The shipping was very fast and the price fair for the 12GB of RAM I ordered. My laptop had no trouble accepting the new RAM and is working flawlessly and super quick now. I would definitely recommend this purchase.

Rating: 5/5 Delivered as advertised August 25, 2014 I bought this to upgrade my Mac mini that I purchased at the same time. I received it quickly and was able to follow the instructions to install it. When I purchase my next computer, it will definitely be from OWC. And I have also made sure to tell my friends and colleagues to purchase their computers here also.

Rating: 5/5 Fantastic purchase June 22, 2012 Works perfectly (I actually tested opening about 8 virtual machines with Windows 7 on them, none lagged), the customer service was prompt and very responsive to my questions.

This is an A grade product and service!
