Rating: 5/5 Excellent products & service as always!! June 15, 2012 Placed order at 5:30pm, paid for overnight and it arrived at 10:15am today, installed and returned to client by noon, she was amazed at the speed. Frankly I am amazed as well at how far the OWC website and ordering process has come from the early days. We do things today with ease and confidence that something can be ordered late in the day and arrive first thing in the morning from halfway across the country. I never even think about reliability as that has been the hallmark of OWC for many years and i just assume it will work without question. Great job Larry and crew, you have built an empire worthy of our trust.

I would recommend this item to a friend!

Rating: 5/5 Installed 2 GB Memory, easy install, works great April 7, 2011 I received the memory upgrade today and looked on the OWC website for the installation video. I could not find the video for the correct model number but I looked at a similar models install video. The installation was very similar and went smoothly. No more than 5 to 10 minutes. The iMac powered up and showed the new memory in the about Mac display window. No problem it just works. I upgraded the memory because my wife is recovering from a broken leg and she can use this older computer since it has a big display and she is primarily using it for email and web surfing. Her immediate comment after the upgrade is that the computer was noticeably faster. Mission accomplished.
