My opinion on this cube is the same of the other reviews here. The turning is very bad: one piece broke after a few turns. I have to say that "Cubedepotusa" replaced the puzzle without any charge, which put them in a very accurate customer care. I don't recommend to buy this puzzle.

The Diansheng 4x4x4 Hexagonal Dipyramid is the bigger brother of the 3x3 version. I was excited to get this; however I was disappointed. The turning was awful and a piece almost broke as a result. The stickers were okay to say the best. Overall, I would not recommend this.

The cube turn really bad, worst than an original rubik's. I give one extra star only for the concept, but do not recommend :/
