How about Yunshuo intelligent micro-projection?

It's the one I've used and I'm satisfied with it ~ It's very powerful, not only for office use, but also for home use. It is very convenient to put a PPT and a promotional film in a meeting at ordinary times. At home, it has more functions, not only watching TV and movies and being comfortable on the big screen. K song, play a game, it's perfect. The price is still cheap, and things with thousands of dollars can achieve many functions. It is definitely a handheld artifact ~ highly recommended.
