Pros: I looked at the HP website for the exact specs of the RAM, and then used the info to buy it here for WAY less. I plugged in the new memory module, turned on the power, and done! Thank you, New Egg for an awesome ordering experience with every detail of the product available! You even mail to APO's... double thanks. And thanks to crucial for the product! Computer: HP Pavilion dv6

Cons: Cons? My mail room thought I had left the country and so it sat there for a couple of days.
