CFMOUR Original Speed Cube 4x4x4, Smooth Magic Carbon Fiber Sticker Speed Cubes, Enhanced Version，Black

I absolutely love this 4x4 Rubik's Cube! The smooth turning and vibrant colors make it a joy to solve. As someone who enjoys a good challenge, I found the larger size adds an exciting twist to the classic puzzle. It’s well-made and feels sturdy, with no sticking or jamming during my solves. The memorization of algorithms is a fun challenge, and I've already seen improvement in my speed. This cube is perfect for both beginners and experienced solvers. Highly recommend it for anyone looking to step up their puzzle game!

I would not call it a speed cube. It looks, turns well, and feels nice, but it doesn't have the best corner cutting and often jams on me, but I do enjoy it. The stickers look cool and feel really good, but they make the cube harder to use. Recognizing the colors is difficult when 90% of the side is covered by black. If you want a cube that functions and looks good, this is the one, but you would have a much easier time recognizing colors with a stickered or stickerless cube.

Moves fluidly and is a great toy

My son hasn’t solved it yet.

Very smooth and reliable

This cube is tiny! Perhaps it was in the description and I missed it, but this cube is only two or 2 1/2 in.³

Good, pretty, cheap
