Repent I did not thankfully. The installation is very easy (by the way I also highly recommended official ceiling mount bought separately), and the picture is super fast set (although no real manual this was - that would have been at the price still in there).
But the most important is the image and that is really sensational for the price! HD looks for HD and the color reproduction is excellent. Especially nice is the fact that the unit is very quiet in operation. My Playstation Slim makes louder sounds than the Epson projector - even though the space is to be found much closer.
The bottom line is I can with certain quality standards only recommend the projector for beginners. More expensive Beamer variants I would not recommend anyway, as will be much improved in this sector in the near future. Therefore prefer to strike again in this price range and then guided in four or five years upwards.
