The bulky package arrived very quickly and well to secure. The housing is tinny, the lateral terminations are made of plastic. Hanging to the eyelets for ceiling suspension, which is a slightly queasy feeling about the load capacity caused me - also because the weight seems to me to be rather more than 4.5kg heavy and also because the coasting mechanism quite a bit of - still jerky - requires traction. But everything seems to be stable enough for some endurance tests. The roller mechanism works well and locks correctly and with relatively light train he rolled out with enough force to complete again.
For me, the height of 2m was important (but not quite roll out - would rather say about 1,95m); not only because I (only very occasionally) for a mobile canvas 4: 3 LED projector use, but above all because it depends practically as (also rarely employed) black-out blind in front of the high window on the ceiling. It is particularly favorable that the back is painted black / rubberized and thus is really very opaque. I think the "rubber" coating is also the source of the penetrating odor (in about the type "new, cheap bonded air mattress"), but detach after about a day with us flew (or our olfactory organs has far as corrosive, that we have seen nothing more). In the near sleeping quarters I do not put something in any case. Something impractical is the quite short clockwork - but you can easily replace if necessary.
Unfortunately for us the canvas has a very slightly wrinkled structure in the middle: a sort of lattice pattern footprint - does not interfere further with our application - but would certainly not for home theater purists. Overall, however, 4 stars from me that are really justified mainly on price.
PS: small tip: the package is secured by relatively stable mounting brackets made of cardboard. The treasury is marking / estimating any hole positions also for the (gross) - not only because of the length> 2m, but also because the angular sides correspond approximately to the distance wall mount for ceiling mounting - just try it ... then you can understand maybe what I'm saying :)
