I’m happy with this! The product is authentic and I had no issues whatsoever installing it and my productivity now is amazing, my laptop doesn’t hang anymore. From 4GB to 16GB RAM, i do not regret this. If you’re considering upgrading your computer/ old macbook go for it!

It was fast delivered the product is amazing my laptop is now faster than rocket ,,,,, works like charm wow.

Great product

Purchased for Lenovo laptop. • Installation was easy, and worked from first boot. • Memory units have now been operating smoothly for over a week. • Rapid delivery from seller. Suitably packaged. Additionally validated the memory in Synology NAS device. Perhaps will procure another batch of same item at a later date - if the NAS requires a boost.

Great product. Just received it and fix it and it makes huge difference

I love it. I can't imagine how fast my macbook pro had become. And its the cheapest I've seen in Amazon so far. Worth it!

Perfect for upgrading your Mac, I used for my MacBook Pro Late 2011 13" and it boosted it speed , highly recommended 👍

I bought it for mid2012 MacBook pro and its works like charm

Works well on my mid 2011 I Mac, went from 6 to 12 GB ram. I will be buying this again to bump it up to 16GB.

Only show RAM, but not working smooth

Funcionaron excelente.

Installed this in iMac (21.5-inch, Mid 2011) w/ 2.8 GHz Intel Core i7 and AMD Radeon HD 6770M 512 MB. Had this computer for more than 10yrs, but hadn't started it up 2019. It powered up just fine at first, then it shut off suddenly and started the 3-beep sequence. I looked it up and was surprised it had to do with memory since I've worked on computers for a while and never heard of that being an issue, especially for Mac. I accessed the memory and shuffled it around a couple times, but the error persisted. These were just a couple of 4gb Hynix modules that had to of been original to the computer. Saw that many were upgrading in excess of the 16gb recommended by Apple, so decided I would try the 8gb stick to see if they did the trick, and OH YEAH they make a huge difference. Even though Apple's not allowing any more upgrades, this thing is blazing with High Sierra. Will be adding another 16gb soon to max it out at 32gb. For about $20 it's a no brainer! If they're compatible with your model I would advise you to grab them ASAP to breath some new life into your old iMac. Next I'm going to work on upgrading the video card and display because this i7 is working like a champ!

Run well after installation to Apple Mini
