Review : Works for MacBook Pro 6,2 (Mid 2010)
After searching for specifications at Crucial's website, I ordered this memory upgrade kit.
Have been using it for two weeks, used some software to stress test the memory and found no problems.
Unless you use memory hogging applications (like virtual machines), you won't notice much difference in performance.
Specs: Macbook Pro i5 2.4GHz, originally with 4GB DDR3 1067MHz memory (note that 2011 models' memories are 1333MHz).

Replacing memory was very easy (although for someone who does this for the first time, it might look difficult).
Have another computer nearby and search for videos on how to replace memory on a MacBook Pro.
Watch them before and while replacing memory. Don't rush, specially if this is the first time you're opening up a laptop.

Also, before buying, make sure you have a screwdriver that fits on those small screws.
