The price-performance ratio of the projector is from my point of view very well. I use the projector for open air cinema in the garden - this the projector is thanks to the high light output along with a good screen (I have a Celexon Economy Line Stativleinwand White Edition 244x138cm 16: 9) very suitable starting at the beginning of the twilight , In home theater use in the darkened living room, the picture also good. 5 stars from me for this good price.
