It's cheap and made of decent cloth, the buttons are in an easy-to-reach spot for my paws (albeit the ZL button doesn't work very well), and it's compact enough to fit in a hipster's fanny pack. BUT the battery life is only a couple of hours. That's why it's best for the kid. Sound, button placement, size, quality of construction, ability to use a standard microSD card, availability of protective cases, portability, autonomy, and game selection are all positives. Cons: low memory capacity, no vibration, no earbuds, weak battery, and a ZL button.
