The design principle may be a bit strange, but is actually quite okay. The assembly is described in the manual, since I rarely read manuals, it took the first time a little longer, but is not quite complicated. If you did it once, it is also in no time. When operating a small blue LED emits forward, but is not particularly bright. Who cares, just tape them off with some black tape.
Processing acts for me relatively high, I use it now for several months already and still can not wear, let alone determine wear and tear.
The installation is absolutely no problem under both Win 7 and under Win XP; all keys and their functions are instantly recognized correctly.
The controls are quite precise mM, just around the zero position gets around the stick to very quickly and very accurately. Overall, the drive fits perfectly in your hand. All buttons are within easy reach, the throttle is however directly under the arm holding the stick, which can be a bit cumbersome. Me personally it does not bother, because it is easy to reach anyway.
One point deduction I give for something low stability. When real grip too weak tendency of stick to tilt slightly to the side.
