better but not optimal

I have now tried all three models of video glasses HMZ.
The new model can be better adjusted than the previous two models, but this unfortunately applies only to the 'fixing' the head. Basically, it is difficult to wear the device without the head - for example on a chair headrest - support. but even so it is to be able to still 'carefree' hard to enjoy in literally a movie.
Add to that the adjustment of the eye distance, here I have succeeded in any of the models to find the optimal setting.
If you think you have the picture adjusted well, presents itself after a short time a slight ghosting (3D) one, which you have to turn wegjustieren, in 2D, I have no experience.
Although I confront the technology really positive, I am in total failed endure a complete movie.

Conclusion: Good idea, but not yet mature in fit and adjustment options - and simply too expensive!
