Pros: Passed Memtest perfectly Works with 2012 iMac No kernal panics in first month Seems to be functioning perfectly Got on sale for $55. Almost $30 less than comparable product from Corsair.

Cons: Lesser known brand. Made in Taiwan. Had slight concern may not function as well as Corsair.

Overall Review: Ran memtest for three passes, first thing. Zero errors. Working perfectly after a month. Great price. Seems to be doing what it is supposed to do.
