In addition to YouTube, Netflix and Amazon Prime Video are pre-installed, so you can watch your favorite anime and movies as soon as it arrives. Old movies that you can't see on the screen now (precious) can be enjoyed on a large screen. The projector has a built-in speaker, so it's all you need in one unit! (Quoted from the official website) Purchased in October 2023. Used about 3 times, but I am selling it because I don't use it often. There are no noticeable scratches or stains, and all accessories are included, but please understand that it has been stored at home.
