Black 2x4x6 Fully Functional Cuboid by Calvin's Puzzle

The media could not be loaded. This is a very well put together puzzle. It has quickly become my favorite puzzle in my collection. It turns very well. It doesn't fall apart in my hands at all, so I don't know what some of these other reviews are talking about. It does have a slight quirk with a couple of the corner pieces: some of them will slide off. It seems that the pieces are nothing more than caps for shorter pieces. It isn't an issue, but you could always mess with someone who wants to play with this puzzle. Overall, I love the build quality and puzzle design and would recommend this puzzle to anyone who has become proficient with other puzzles and would like a new challenge. Also, don't give this to a twelve-year-old.

This product is very cheaply made. My 12 year old son was playing with and and dropped it (slipped out of his hands) and crashed into a million pieces. We re ordered it and the pieces fell apart in his hands.

Good, but the stickers are less than desirable. I love the cube, but the stickers require a little TLC to keep them from coming off.

Buen cubo aunque cuesta mucho girarlo, no es del mejor material

It's a very good puzzle. I've been playing with it for I dare say 6 hours or so and I've had one piece pop. I put it back in and it was all fine and dandy again. It's incredibly challenging so for newbies this is a cube to avoid. It's interesting, to solve this cube because you have to solve it like multiple types of cubes at different times. All together, great cube and pro tip, don't give it to your 12 year old son.

Excelente giro, recomendado!

Los stikers estan mal pegados y se salen.No es lo que esperaba de un cubo de esta calidad.

Very good
