I have to agree with Blue on the open puzzles...
Luckily I already have my Isis open as well, or I might have been disappointed on seeing it completely revealed. Part of the fun is finding out what the internals look like, as a "reward" for solving the puzzle.
For the Ramisis, I don't own one yet (found the prize up to now a little steep, although I'm still contemplating it, with the current offer of the 15% off when buying it together with the "new" NKryptor...) but having a look at the chamber out, already "spoiled" part of the fun...
Not that it is *THAT* much of a deal, as it doesn't give any hints on how to get there, but just that little bit of the "magic" is now gone. (When reading the posts of people opening up the key chamber, I had, in my mind, a completely different picture of what this chamber might look like

)
