Really a nice projector, not quite small (there are much smaller at 500 lumens, also the power supply east rather a big block), but OK. Light intensity are nunmal 500 lumens, which is not the world. But is also OK. Schön is the battery pack, but then come no more to 500 lumens - a pity. Only two things were really annoying (and reason for the return): Miracast and the projector during operation are slow. Miracast delayed much longer than other projectors (Dell) or adapters (Netgerar) - and that bothers genuinely with PC projection. And then the colors are not good. The image is emphasized red-much to. That was hardly turn off, no matter what setting you take. Real, because I praise the two Dell LED Beamer. The one with the colors seem to be an unfortunately very common problem, this would have to be as simple just with LED ...
