Currently, the sarcophagus arrived and I can tell you: He fits in! :) The 2 rubber bands to hold the Ds fixed, are not as annoying as some always describe here. I do not find particularly bad that you sometimes just need a few seconds longer to the 2 rubber bands to lift and push the 3DS underneath. That would be already bleating at the highest level. ;)
The build quality is superb and the DS slips only minmal a little bit, which is not bad in my opinion. All in all I am very to peace with the case and would recommend it.
Now I need also not be afraid if Kitty accidentally again my 3DS throw from the cabinet. :)
