The case is more rugged than I expected. The included heat sinks are really nice. The keyboard didn't get shipped initially but they were really responsive when I let them know.
The keyboard is compact but the keys are spaced normally and the mouse is flat but it's beveled on the sides so it doesn't feel like it's gonna get away from you.
I run the Pi off of an 8A ONN battery pack from Walmart and it works great.
