Its' a good cube, I love using it. Only downside is that it's bigger than the MGC.
I would recommend also getting the YJ 56mm 4x4 to supplement it.
This cube is amazing and breaking my PB like everyday and when I got this cube I went to comp and got my first sub 1:30 average.
Compared to other 4x4, this cube has great magnetics. Love the ease of turning with speed on this one.
I love this 4x4. it might be because this is my first 4x4 speedcube but i think its great for its price. The shades are nice and the magnets help a lot for me. The corner cutting is okay but i'm sure if you loosened it then it would be better. overall, its an amazing cube and I recommend it to anybody especially if they are starting 4x4 or want to get into 4x4.
