Pros: -Doesn't run any hotter than the stock mem in my mid-2012 MacBook Pro. -Price. There isn't much in this price space that seems to be worth the risk, but this stuff delivers. -Game performance better since the upgrade.

Cons: -None so far. It has passed both mem tests that I have run and doesn't seem to be running any hotter than the stock RAM in a laptop that is notorious for running hot.

Overall Review: I'm a data storage and virtualization consultant, so you can imagine that I tend to put a bit of stress on my machines at work. That stress is probably multiplied by the gaming that I do with it once I get home (through Bootcamp, of course). This upgrade has been solid and allowed me to get quite a bit more out of this laptop. I highly recommend it to anyone that is looking for 16GB RAM on a budget.
