DaYan JingHong 4×4 M (Magnetic + Ball-Core)

The DaYan JingHong 4×4 M comes in a compact white and light blue box containing the cube itself, extra springs and an instruction manual for learning how to solve a 4×4. The cube features primary internal plastic, allowing you to see deep into the mechanism and its magnets if you slightly spread the outer pieces apart. Straight out of the box, the puzzle is tensioned just right while being fast, smooth, and very easy to turn, something which is a major plus for 4×4 cubes, as achieving peak performance can otherwise be a bit fiddly. However, if you do wish to adjust the puzzle, you can do so using a standard screwdriver on the screws visible at the center of each face. The puzzle corner cuts well, is pop-resistant, and offers a generally medium to strong magnetic feel that easily keeps the layers aligned during solves. Simply put, it is a high-performance 4×4 cube suitable for cubers of all skill levels.
