Please note that some new cubes when being used for the first few times may experience what is termed a "pop". This is when one or more parts of a puzzle pop out without any damage actually being done to any of the pieces. This also occurs from time to time during normal usage. Pops are typically not considered a defect if the parts which come off can be reassembled by hand.

Tensioned and balanced out of the box, this puzzle turns super easily and makes it a blast to mess around with. I have not managed to finish it yet, but cuboids always give me problems :). The puzzle itself is really impressive, shapeshifting into a lumpy amalgam of cubies sticking out every which way, and really is a treat to fiddle with. It does not feel fragile, even when turning a face that is not able to be turned (like an unfinished face) it feels sturdy. Not sure if this cube really needs to exist though, with all the other X-Cube type puzzles out there now. I would start somewhere else and if you end up liking it, purchase this one next! Or start here, it is already great.
