Rating: 5/5 Good priduct and exceptionnally good customer service March 30, 2016 My experience was buying this 24Gb RAM ugrade for my MP 5,1 6-core 3,33Ghz, which I had been looking forward for a long time (also highly upgraded the GPU last month). The product is as mentioned, was installed and works like a charm (although I believe I was already confortable with 12Gb of RAM, I noticed some RAM page outs lately using Photoshop CS 6 / Capture One / Firefox). Now what happened is that the package got stolen in my mailbox and that it was difficult for either service (OWC/Macsales and the French postal service) to assume responsability for this theft. Nevertheless, having proven my honesty in this situation, Macsales took it to them to send me another pack, at the one and only condition I accept DHL (and the customs fee, about 1/3 of the total price in the end, but still worth it). I must pay total respect to the quality of the customer service here which helped me from A to Z. Cheers ! And to those that order from EU for example, I strongly recommend using the trackable and person to person delivery exclusively. Too much theft in mailboxes in Paris these days !

I would recommend this item to a friend!
