Rating: 5/5 Extremely competent customer service and superb product March 29, 2016 Prior to purchasing, I had a live chat with a very competent service person who guided me through the intricacies of RAM selection for my MacPro 2010.

I wanted to max out the RAM and the advice I received helped me a lot to secure the correct memory reference for purchase.

Shipping to Europe was a mere matter of days and the RAM worked out of the box providing the announced performance.

I'm very satisfied with both the product and overall purchasing experience.

Definitely recommended to european customer who want competent input prior to issuing an order.

Rating: 5/5 Out with the old, in with the new. March 1, 2015 I'm a long term OWC customer. My 2010 6-core's 3x 8GB OWC chips needed a memory refresh for Yosemite and the Adobe CC suite. With the purchase of 3 x 16GB chips I received a 3 x $40 credit for my old chips. The great thing about purchasing memory from OWC is support. If there is a problem they will take care of it. No worries.

I would recommend this item to a friend!
