I got this from PuzzleMaster but kept it away until a couple of months back when I saw Kevin's review of it in PuzzleMad. There is also a write-up of a wooden version (called the Exploding Cube) by Allard of Puzzling-Times. This is a take-apart type puzzle and both gentlemen have stated that this is relatively straight forward. I couldn't agree more. In fact when I was removing the puzzle from of its packaging, I actually could feel the pieces trying to disengage themselves.
It is also a pity that the "curly" shape of each of the 3 interlocking pieces are formed by fusing of two other separate pieces together, resulting in join lines which are very visible, even externally when the puzzle is in the solved state. (See Kevin's photos on his site). I think with the wooden version, these lines are probably less obvious.
