              Did What They Said, When They Said, For The Price They Said

              By Joe

              from Yuma, AZ

              The chips arrived when they said. The enclosed invoice conformed to my telephone order. Both the printed instructions and You Tube directions were straight-forward, the process taking about 5 minutes. And the results were VERY noticeable, on all programs and operations.... For about 25% of what Apple would have charged me pre-installed. Kicking myself for waiting so long.

              I ordered two sticks of memory. The parcel arrived in a timely manner. Adding the two sticks was a breeze and my IMAC is running like a brand new machine.

                          These memory modules worked great for my iMac Mid 2011. The computer was running slow with the 4GB memory. When I added 8GB of memory it was an amazing improvement. The computer is running like new and I can have many applications running simutanelusly.
