This is a second-generation model, so it's quite old, but it's in good condition (probably only about 30 hours of actual use) because it was kept in an AV cabinet in a pet-free, non-smoking environment and used infrequently. Of course, it's fully functional. However, it's a used product, so please refrain from purchasing if you are overly concerned about its condition. It supports Wi-Fi, AirPlay, and even wired LAN, which has been omitted from recent models, so you can use it stably even in an environment with unstable Wi-Fi. #HalloweenOnMercari
