The MF8 2x3x4 is a fully-functional irregular cuboid in that no two sides have the same number of cubies. It turns smoothly out of the box and features solid construction.

Update: As of 20 Dec 2014, the MF8 2x3x4 is fully functional out of the box. It no longer requires extra internal parts to be installed to make it fully functional. Therefore, we won't be including the extra internal parts anymore.
