Rated 5 out of 5 by from Great Stuff! Installed two units in my iMac and bingo, works like a charm. I also like the packaging as I live in a rural area and sometimes things get damaged enroute.

Rated 5 out of 5 by from Great addition to my new 27" Retina iMac I use my computer on an every day basis so getting this new RAM was a great investment so I know my computer will have enough memory to withstand some high demanding applications. The iMac came with a stock 8GB (2x4), but now that I got another 8GB kit my iMac now has 16GB of RAM which is fantastic!

Rated 5 out of 5 by from Great product, great price, and fast processing shipping Had to wait a little for the testing to be complete for this product on a new releases iMac 5K, but the wait is worth the price difference from other competitors.
