Just, always know, someone else is doing the same thing only better. That is why they share with one another. Say, patented cooling, for exchange of better lumens, say Akyumen's 35-40 lumens and Texas instruments 5000 lumens, clearer yet. But can you keep it cool enough. For any length of time. That's the problem with projection it gets hot. But I have a feeling it's going to get better and better. The mobile device projector and all is the bombshell for all video,gaming,communication record projection into the future. Nice device to own.
