Rating: 5/5 Buy your memory at OWC! December 19, 2017 Whenever I need to buy memory, I always turn to OWC. As always, their service was fast, and their descriptions make it very sure that I'm buying the right memory for the right Mac. In this case it was for a 2009 Mac Mini, so it's not something everyone carries. But I always have the confidence that if there is ever any problem with the modules, I can get it promptly replaced, no questions asked.

Rating: 5/5 What a bargain September 8, 2016 I was looking for something else but could not pass up adding two cards at this price even though I didn't really need it. Look at the video since the tabs are a bit tricky.
