Because the water level is placed on the hot shoe, there any scope changes the result. You can assemble the cube in two directions, but when I turn it changed the result, and a seemingly horizontal alignment appears as a slight incline.
Although the water level is stuck very beautiful, and looks well made but of this inaccuracy is to imagine, especially I do not know what result the "right" is when I turn the cube.
Conclusion:
Beautiful part helps in aligning, but unfortunately somewhat imprecise (as might be expected in this construction was) and points deduction due to the different results as mentioned above. I'll keep it anyway as there are apparently no better solution, but am fankbar for any hint in this direction.
(The packaging and the "manual" way, is purely in English, which is not a problem for me, I mention it yet, for some this may be a problem.)
