It's better quality than a nintendo ds, no joke! the hinge is better, since it's an open hinge, meaning you can adjust it to any angle when playing and it stays put. i would recommend getting the linux version or installing rocknix on a separate sd card for more efficiency when playing games. battery life is around 5 hours on pokemon, and the charging is very slow unfortunately, i haven't found it to be an issue because i charge the device overnight. overall a very fun way to play ds games, and it's super fun to install pc ports on it as well.
