Rating: 5/5 Good Experience March 12, 2016 The whole experience buying the memory stick is pretty good. And not to say the quality. At Jan OWC is probably one of the only places I can get memory sticks for my late 2015 model iMac 5k, and the memory worked just like a charm when I stuck them into the slots. It has been functioning for almost two month with 24 * 7 up time, and nothing funky had occurred. BTW, they even have a service to collect your old memory sticks, I haven't tried because i ran my old stick with the new ones bought from OWC.

Rating: 5/5 Great upgrade at great price March 8, 2016 I ordered this 32GB RAM upgrade kit to supplement the 8GB RAM that came with my iMac 5K (late 2015). By configuring my iMac with the minimum amount of RAM when I purchased from Apple, I save some cash—and the first thing I did after ordering was order this kit from OWC. It's a no-brainer.

Pre Delivery they were very quick at replying to any concerns I had, I would order from OWC again, and would recommend to any mac user who wants to buy memory or any related products.

Rating: 5/5 Total satisfaction! March 2, 2016 I am satisfied with both the product and services from MacSales. The product arrived on time and with no problems. After reviewing the video provided on the MacSales sight, I was able to install the ram: which took just a few minutes. I have upgraded from the original 8Gbs of ram to 32Gbs. This gives me the ability to have more instruments open in my recording workstation at one time without any dropout. Dream come true!

Rating: 5/5 Works as advertised March 1, 2016 Apple website claims the iMac can be outfitted with maximum 32 GB of RAM. OWC says the iMac maximum RAM is 64 GB. I installed 64 GB of OWC RAM into a new iMac and it indeed works. Fast.

Rating: 5/5 As Tina Turner would say - Simply the best! February 25, 2016 This is the second time that I have purchased RAM from OWC, and frankly I would not dream of buying from anywhere else. Great prices, arrives quickly, wonderful installation tutorials on their website and ease of locating what I need - flawless!

Anyone who does not buy their computer supplies from OWC needs to seriously think of getting some more RAM for their cerebrum.

Rating: 5/5 Great Price and Performance! February 4, 2016 As I spec'd out my build-to-order (BTO) iMac w/5K retina display, I balked at the $600 Apple premium for 32 GB of DDR3 RAM. I knew I could find a better deal on compatible memory at OWC! And that I did - and saved $400! It installed easily, performs flawlessly and I even got a rebate for the 8GB stock RAM I traded in!

As always, I HIGHLY recommend OWC for all your aftermarket Apple needs!

Rating: 5/5 Prompt and efficient January 17, 2016 I inadvertently purchased RAM for an earlier 5K iMac, not the latest one and requested a refund. Even though I had opened the packaging, OWC credited my card with the full amount minus postage within days, no questions asked. I am very impressed with the service and can't recommend them highly enough. Needless to say the correct RAM works perfectly.

Rating: 5/5 I saved a ton of money! January 13, 2016 I love working with OWC and their staff. They have been taking great care of me and every Mac I've ever owned. I recently bought the 2015 27-inch iMac and came directly to OWC to put the finishing touches on my Mac.

The 64GB-RAM upgrade was a solid investment and the money I save shopping at OWC keeps me coming back.
