Rating: 5/5 easy peasy upgrade, and well worth it November 27, 2016 The upgrade was super easy and well worth it. I upgraded from 4G to 16G of RAM and included a new SSD with the upgrade. The memory upgrade alone made my MacBook Pro like a new machine - much faster and seems much more reliable. When the SSD was added - WOW - it's Super fast. Definitely recommend MacSales.com. They have good prices, they ensure the upgrades are compatible, they deliver fast, and they have videos that help a lot with DIY upgrades. I couldn't be more pleased.

Reviewer: Piccolo Location: Oakland, CA Age: Over 65 Experience Level: Home User Owned Product: 3-4 months
Rating: 3/5 Not very much faster November 26, 2016 My current MBP (~3 years old) had 8GB RAM, but seemed slow to me. After my excellent experience after upgrading other MBPs with OWC RAM, I purchased the 2X8GB upgrade kit. Why installation was easy, speed-up was not as expected. Maybe, I'll replace with HD with a Mercury SSD.

Response from MacSales.com, Technical Support November 28, 2016 If you're doing memory-intensive processes, then having more RAM will speed up those processes. If you're looking to get faster read/write speeds for data, then a SSD would help.

Rating: 5/5 A pleasent surprise November 21, 2016 So since ive upgraded my mac os to siera on my MacBook pro, i've experienced horrendous slow down and lag. The lag was so horrible that it couldn't hardly launch the web browser. So then I've checked the system profile and realized that my mac only has 4GB of ram. So I've decided to upgrade the RAM and max it out to 16GB. I've ordered 16GB of ram from macsales and once I've installed it, i was shocked. The performance was like night and day plus start up time was decreased significantly. I can now multi task and play videos without any hiccups. I truly thank macsales for such an awesome product.

Any application especially the app store would take take literally more that 2-3 minutes to come up. All that is fast and smooth now. Rebecca of macsales was very helpful and knowledgeable. She helped me choose the right product and impressed me with her knowledge. Delivery was super fast and though I chose teh cheapest shipping option. The parcel was in my hand (in Singapore) in 9 days. Overall an excellent experience and highly recommended

Rating: 5/5 Perfect to extend the service life of my older Macbook Pro October 31, 2016 My 2012 Macbook Pro 15" was starting to feel seriously outdated. Applications were slow to launch and would often bog down. I really can't afford a new Macbook Pro, so I looked at my options for improving its speed. I decided that maxing out the RAM would be the most cost-effective solution and I couldn't be happier with my purchase. My computer boots up and runs applications very quickly and smoothly now. Well worth the money spent on this upgrade! Very easy to install - just needed a small screwdriver and about 2 minutes of my time.

Reviewer: UnknownPurchaser
Rating: 5/5 So far so good! October 25, 2016 It's been a few months since I installed the RAM upgrade on my MacBook Pro. I followed the installation video from the website and it was a breeze. Only recommendation is to be careful taking the old RAM out and putting the new RAM in because it seems sensitive and make sure you hear the clicks! The RAM registered perfectly in both ports and I am happy to say I have had no issues thus far!

Only bummer was that the selection I made didn't come with the hardware to do the install so I had to go out and buy some. Not a problem but maybe I missed the option in the order or chose the wrong package.

Great product nonetheless.

Rating: 5/5 Memory works flawlessly October 24, 2016 I tried adding some cheap third party generic memory to my 27" Retina iMac and it caused nothing but trouble -- spontaneous reboots, kernel exceptions, and corrupt data being written to the drive. I finally broke down and ordered this add-on kit to complement my existing factory installed memory and it's been smooth sailing ever since. Not a single glitch since the installation. I can't recommend this kit highly enough. Well worth the price (and considerably cheaper than having it preinstalled at the factory).
