Rating: 5/5 Perfect! April 24, 2016 This was my first time ordering from OWC. I'm more than satisfied. One of the things I like the most is that you don't have to worry about compatibility issues. No need to guess. The website just tells exactly what you need for your Mac model. The package arrived in time and was packed very well. Installing RAM was a piece of cake thanks to the videos that explain the process in details. Everything works just fine. I would definitely buy from here again once I need anything else. Highly recommended. Thank you OWC!

Rating: 5/5 Easy and simple! January 21, 2016 As far as performance goes I think going to the SSD gave me super speed...but more RAM never hurts! OWC, from all my reading of reviews on Amazon, IS THE WAY TO GO for plug and play. It took me about 10 minutes start to finish to take out old and install these cards. It is so easy! And the price has come down so that its a cheap way to upgrade your MBP. I was careful to discharge static on an electrical outlet, run a humidifier, and do as Apple says on their RAM upgrade install to handle static. Very satisfied!

Rating: 5/5 Easy "plug-n-play" ... no hassle installation September 14, 2015 Not being tech-savvy, I hesitated somewhat to purchase extra memory for a brand-new, 27" iMac. OWC's video guide made installation appear easy enough. I think the hardest part was popping the cover off the computer. Enjoying glitch-free, fully-compatible performance. (I hope I don't jinx myself. Chuckles!!)

Reviewer: Anonymous Location: Chicago suburbs Age: Over 65 Experience Level: Power User Owned Product: 1-3 months
Rating: 5/5 Perfect fit. Job went smoothly. August 17, 2015 I purchased the 8.0GB (2x 4GB) PC3-12800 DDR3L 1600MHz SO-DIMM 204 Pin CL11 Memory Upgrade Kit for my 13" summer of 2015 Non-Retina display MacBook Pro (MacBookPro9,2)

The memory arrived in about two days via USPS with free shipping. (I should add that I live within 30 miles of OWC in Northern Illinois.)

The back of the non-retina MacBook Pro is secured by 10 #00 Phillips screws. Three of the screws are long (about 6-7 mm if I remember correctly) and are easily distinguishable from the seven shorter screws (about 3-4 mm). However, the shorter screws consist of two sets of 3 and 4 screws, which have the same length but have different head shapes. Close inspection of the heads of the shorter screws will distinguish the difference. Be sure to keep the two sets of shorter screws separate.

I used a pill box (with compartments marked S,M,T,...,F,S) to store the screws after removal. A magnetized screwdriver also helps.

I also used used two "spudger" tools (yes, that's how they are spelled in any computer tool catalog) to lift the battery terminal from its socket and to help seat the replacement memory. The two spudgers are not absolutely necessary, but they do help.

The original 2 x 2GB memory chips are held in a spring loaded clip. When the springs are pushed aside (with thumbs or spudgers), the clip springs up 45 deg and the chips are easily removed. The replacement memory can then be slid into place and thoroughly seated using the two spudgers to simultaneously push each end of the chips. The terminal is then pushed back down to the board.

I had no trouble seating the two 4GM chips from OWC into place. They seem to be the exact same size of the original chips, although they do look different.

The whole process took me about one-half hour, but I work slowly and wanted to poke around to see what could be easily replaced in the computer. (The HDD, DVD, and battery are serviceable, although only with a specialized screwdriver.)

The job could easily be done in ten minutes if time were important. It was an easy job and went smoothly. I am thoroughly pleased with the OWC memory set.

Rating: 5/5 Well done. July 3, 2015 It's now unusual to find a business run so well as Other World Computing, and it deserves your consideration. The website is superbly written and designed to make ordering and followup easy and understandable. Emails with tracking information linked arrived moments after the order was placed. The order arrived a day early, and the product performs as advertised. Price is competitive with any other vendor I could find, and I'm left with the feeling this company values its customers in the way businesses in America did when I was growing up. You have my compliments and future business.
