"Worked in 2 minutes after download!"
Easy once you know how it works.
Lots of options for video quality (haven't tested them all yet)
Not the best file structure. Sometimes hard do find something if you don't manage your folders well.
So far, I'm pleased. You also have to know that it is a playstation and it's not really made for being a full options media hard drive. Keep that in mind, and you'll be satisfied.
