Rating: 5/5 Perfect Purchase As Always October 11, 2016 Doubled my 8GB memory and see a little faster response when using several programs running at once. Easy install and as always fast shipping and service by Macsales.

Rating: 5/5 Couldn't be easier! July 4, 2016 Very happy that the iMacs' memory continues to be easily upgraded, and OWC makes it as easy as can be with explicit step-by-step instructions; 5 minutes tops, start to finish. Do this every time I buy a Mac desktop, have saved hundreds and hundreds of dollars over Apple's installation & parts costs.

Rating: 5/5 The Only Place to Buy RAM June 23, 2016 OWC is consistently reliable. The RAM always arrives well before the projected delivery date, works great, and is easy to install thanks to their helpful videos. Their webpage makes it simple to choose the RAM you need.

Rating: 5/5 Arrived shocking fast. Great value for performance. December 15, 2015 This RAM arrived much faster than advertised, which was a pleasant surprise. It's also been a great performance value for the money for my late 2015 27" iMac.

Rating: 5/5 Great memory products December 4, 2015 This is the second time I have purchased OWC branded memory for another iMac. Their memory products work with no complaints, even in just on the market new iMac models. A friend bought a "name brand" memory modules for her computer and it failed after a couple of months. I have always been happy with my OWC products!
