The screen complies with the requirements. Remember you should but that the canvas exhales heavily after the first unrolling. the solvents used may not match our German regulations. In our case, we could then not use the meeting room (about 25 square meters with about 3 m high ceiling) three to four days, as long has the evaporation of solvents or plasticizers lasted. It is recommended that this schedule egg after assembly and to be rolled out during this time the canvas.
When fitting and adjusting the lower Ausrollpunktes we noticed that the Podi required for this is very difficult to achieve with the supplied flexible "alignment rod", we had to ensure the canvas again depend first and already begin to "alignment rod".
The engine is very quiet and the screen rolls up only the right and left edge just a little bit (in the range of the black border).
