This cube has potential in their idea of customizing internals, I really love the concept!
In my opinion, the feel to the cube is very smooth and fast, the magnets are perfect in strength, and love the internals to it, also the fact this cube has this soft texture to it when holding it. The tensioning system is pretty straight forward, though some of the pieces are easy to lose if not careful.
Overall, this cube is very good in performance and design! I would recommend it to others for those who want a customizable, unique speed cube!
