After I unbox it, first few turns felt dry. I thought that the factory lube wasn't added but it was there, just needed some turning to spread it through.
One week of usage and I've realised somethings about this cube.
1. [Glossy finish] Makes the cube a bit slippery
2. [Lubing] I added about 1 ml of cubelelo velocity and about 30-35 solves later, feels dry again. Being a big cube, it uses lube a LOT faster than a 3x3
3. [Magnets] The outer most layer will have the weakest magnet and the inner most will have the strongest. Which is useful.
Just a bit bigger than you'd like
Good one in my op👌
