All the three cubes are are really great. The 3*3 is an underpriced cube, it has some great corner cuttings and incredible rotations. The 2*2 is also another amazing. I'll grade it a 9/10 cube. The 4*4 is not smooth much but since its my first 4*4 cube, I dont have much to judge on it. Overall, its actually a great steal deal at this price
