Rating: 5/5 Product performance as expected. October 8, 2018 The two cards arrived earlier than I expected, within 14 days, and were appropriately packaged. Installation was as per their instruction video and working really well. Simply cannot fault the whole experience what-so-ever. Also had no qualms that the correct RAM cards were ordered, as OWC explain the relevant parameters very comprehensively. Thank you for a seamless experience.

Rating: 5/5 More Memory July 3, 2018 Installed in a Mid 2011 27" iMac to bring it up to 32 GB. Simple installation and works great. Later install of a 1 TB SSD has made this "old" system a rocket ship after install of High Sierra and a clean up. I would recommend everyone upgrade their memory (if possible) to the max!

Reviewer: NicholasGMS Location: Singapore Age: 45-54 Experience Level: Power User Owned Product: less than a month

Rating: 5/5 Excellent product! June 22, 2018 Order was placed on Tuesday (19 June 2018) afternoon and I received it on Friday (22 June) morning. I'm in Singapore, by the way, location of the inaugural Trump-Kim summit. I chose DHL express. Product was very well packaged. Installation was a breeze. Took me about 5 minutes to install on my iMac 21.5" (mid-2010) and restarted without a hitch. 'About This Mac' read "16GB 333 MHz DDR3" right away. Desktop file icons appeared instantaneously as soon as desktop appears - this has never happened before. Normally, beach balls turns and turns for a long time before icons start to trickle in, but this time, it was like Boom!, all there and refreshed with the respective document icons. I can feel the overall performance of my iMac is now speedier even with many applications opened at the same time. Clicking on any folders will display file directory at once without having to wait for comp to 'think'. I'm very happy with the product. Thank you OWC. I highly recommend this product!

Rating: 5/5 Excellent Product/Service & Easy to Install June 5, 2018 I nervously ordered 32gb of Memory (consisting of 4 modules) for 2012 27" iMac. (Apple says this computer takes up to 16gb, but it actually works better w/32gb). I wasn't sure that I could install it myself. But thankfully OWC has a video that shows you how to do it. At first I had a lil trouble. I called Customer Svc & they gave me some tips. Tried it again & it worked like a charm! It turns out I hadn't pushed it in all the way.

Very happy with my order! I'm now waiting for my rebate check.

Thank you!

Rating: 5/5 My goto site for breathing new life into old Macs. April 30, 2018 I've discovered the good practice of rebuilding old Macs, and OWC is without a doubt the only place to go to for completely compatible parts to turn these old used Macs into new powerhouses. The prices can't be beat either. You would easily spend more for "questionable" parts from other sites. Thanks OWC.
