In accordance into it annoys me that I have not yet spent 5 more, because the quality is not so great. That the body is made of plastic, is clear. Unfortunately, even the thread of the locking screw of the shield made of plastic. Once tightened a bit too tight and the thread is gone. I had expected there at least one metal thread is incorporated as in the bottom screw also.
The metal spring in the hole of the shield attitude that should fix the screen is somewhat interrupted me in the first test the same. But really important, it is not anyway, so ... no matter.
A positive feature is the spring-loaded jaws of the flash bracket. These are pressed by springs 2 when loosening the screw. This is an unnecessary luxury, the other manufacturers have solved more price-conscious.
Overall, the flash picture is much too long with about 5cm. Half would have been enough. This is waste of material and makes the umbrella Eiger unnecessarily difficult.
The slope can be "almost" infinitely varied. There successive press 2 toothed discs, so that the inclination every millimeter locks a little. That feels good, and so the screen can also be at a greater burden not to sag by a heavy shield. But because the discs are made of plastic, it is up to the 2 discs have worn smooth only a matter of time. Again, a piece of metal would be more appropriate.
Now, as a substitute, it is "ok", so I have not returned to him, but would not buy it again.
I can recommend the Eiger screen only for the occasional user, where it really matters to the price. Because the price / performance ratio fits and fundamentally bad the product is.
