Positives: reasonably stable metal construction (pipes, stand, etc.) with a few equally stable plastic parts (plastic caps on the legs, robust carry handle and locking lever made of plastic).
The 4mm thick metal rod with which one (also plastic) mounts the raised screen top center on extendable hoes, has been solved in some improper handling on one side of the anchor (small riveted sheet metal): by straighten again Plug and fix again with blind rivets again I could easily fix it by yourself.
Quite flexible: lower edge and upper edge can be continuously and independently from each other varies in height.
Even at maximum extension upwards (enough just to our ca. 3,50m high ceilings): is the canvas on the stable three-legged on floor. For deep-pile / irregular carpeting or not exactly horizontal or yielding soil, I would advise against it! Also you should make absolutely sure that no one (especially children) comes too close and accidentally brings the screen to tilt.
Negatives:
Large weighing several kilos: the drop can probably substantial injury / damage to bystanders / objects occur!
Also putting up, even with some practice some fumbling (the detriment of flexibility in the height adjustment) and due to the weight alone of the heavy and also provided with return spring canvas requires a not inconsiderable force (with one hand, the retractable holder on the bottom edge, press downward and with the other hand pull the rail to the upper chopping up and then finally the locking lever of the upper edge Around). Have a second person to help is strongly recommended!
Slight twisting and tilting the projection surface and slight rolling of the right and left screen edges can be compensated by manual corrections something - but keeps also after my little perfectionist view very limited and hardly disturbs.
When cleaning the screen is drawn into the box through the spring and then turned the box vertically, whereby one must be sure to turn the end of the box with a small hole for attaching the remaining linkage on the right side: as this but in This item is out of sight it is quite fummlig to pfrimeln in a vertical position the small arbor at the top hacking into the hole of the box: may you put better everything carefully horizontally on the floor.
The three legs tremble when folded and walk while wearing like by itself again, so I made from tape a cuff that is now pushes on the folded legs and in front of the building simply pulls upward. You could also be attached to one of the legs, a band with Velcro. Why the manufacturer did not think of that?
On the whole, this canvas is to be assessed for non-daily assembly and disassembly of me as inexpensive and reliable.
