I do not regret my decision.
Installation instructions was there and was quite understandable
Power connection is the way to the right! For me, unfortunately, wrong, but one can lay a cable duct.
The screen moves quickly in and out, setting the screen is a little trial and error, as you have to turn on a set screw (one revolution = about 2.5 cm) but also that's done fairly quickly. If, just about one and adjusts the projector on it.
Fasteners and screws have a very high and stable.
The smell is really annoying, but probably evaporate (has already become less)
Please also want to dispose of the packaging box quickly and not stored in the home or even cancel. The stinks!
I think: cheaper and better you do not get in the size !!!
