Pros: Works in MBP 15' Mid 2012, Nice CAS latency specs, easy to open package *shrug*

Cons: None so far

Overall Review: I was concerned that the memory would not work with my MBP and some of the reviews here at newegg said it did but they weren't exactly specific about the MB model. After installation, the MBP booted up without any problems. I've only had it installed for less than a week and there hasn't been any problems yet. I'll make sure to update the review if any freezing occurs. Using the new Parallels 10 is still slow but I think that's because of the software and not the memory. A little fine tuning may resolve the issue. At least activity monitor's memory status doesn't turn red from using up 7.9+GB out of the 8GB I had to work with from before. So far, I'd recommend sticking with bootcamp (for Win8.1) if you are thinking about switching and upping your memory. This may change later as the Parallels team updates their software regularly.
