What do the “honeycomb” surfaces in the MonsterGO 3×3 do? On the inside of the cube, the contact surfaces have an engraved pattern instead of a smooth finish. This pattern gives a unique feeling in the cube that GAN’s cubes have become known for. In addition, this surface ensures that lubricant is distributed evenly within the cube and that lubricant will last longer. The cube has a simple, beginner-friendly system for adjustment. Under the center pieces you will find a so-called GES nut. On this nut you will find two positions, 0.6 and 0.8. By default, the cube is set to 0.6 and can be changed to 0.8. To adjust, press the nut down slightly and turn it to the desired position.
The cube is also available in a magnetized version, see here.
It is very good.
