I bought this a few years ago for an event, but it was canceled due to COVID, so I only used it for testing (20 minutes of use). The image quality was good enough for watching YouTube and movies. Subtitles are also easy to see. It has a dial design that makes it easy to focus. I projected from my smartphone and tablet, and there were no problems. Connecting an Amazon Fire Stick was also no problem. Connecting a game console was also no problem. Connecting a PC was also no problem. Connecting an external speaker was also no problem. No claims, no returns. Free shipping.
