because this is my first canvas, and also my first home theater system I can not make comparisons, but tell only a few points.
Shipment:
Very quickly, within two days of the canvas (Shipping with TNT, dispensing with the neighbor) was my return from work at the door. No appointment with carriers or the like.
Assembly:
According to the manual, we should hang them on hooks for ceiling mounting. However, the result was a wobbly housing, where you could take off the canvas not tidy. So we decided afterwards to mount the screen directly onto the ceiling. Now everything is stable and tidy. Here you can see the instructions so safely ignore.
Operation:
The canvas is absolutely straight with us and can be very wide and easy to pull out. It may make you snap every couple of cm and thus determine the size of the canvas. Waves I did not notice, maybe I did not sleep well for it. For me, this image is absout top on a flat surface. Currently they still developed a slight smell of oil, but it is already less.
