Awesome cube to have and play with. It turns smoothly and nicely feel in your hands. Not too hard to solve at all. It's one of the best Ayi cubes I'd say.

This is my favorite Cuboid. It is awesome! First you get the centers on each side. Then you edge pair. Then you solve it like a 3x3x2. Parity also makes it more challenging. I definitely recommend this puzzle. I can ever speed solve with it because of its great quality.

The Ayi 4x4x3 is a great puzzle to add to your collection. The stickers are good quality and will not chip unless you do not take care of it. The turning is good as well and the edges are nicely rounded so my fingers will not get sore. Overall, it is a great puzzle and I highly recommend it.
