Two weeks later the package arrived in the form of a small envelope with bubble wrap. The structure was Ihne instructions somewhat cumbersome and contrary to Google's Cardboard there was here 2 or 3 items while Google is a complete piece.
What was the first bit disappointed me was the fit which was unfortunately, in spite of having ordered head mount, not at all given.
The disappointment, however, was quickly dispelled after the start of the first Cardboard App. After I had found the right position, I had a class VR experience (! I say this in spite of my Occulus Rift experience!).
Since I am the owner of a Galaxy S4 does the magnetic unfortunately only partially, but there may indeed Andoer not help it.
The lenses are good and clean, the Cardboard se acts after assembling stable. Other reviews made here about stability were just too impatient to get it right.
Unfortunately, the holders for lenses and magnets are moved slightly and the inner magnet falls like to get out (but with a small strip Tesa no problem)
The perspective sometimes not true but cardboards are just a mass product and not throw accurate to eye relief and so adapted.
All in all a great experience and a good start in the Virtual Reality.
Would recommend it immediately further.
