The GAN 330 is king when it comes to compact speed, but this thing is great for really training those algorithms into your mind and muscle memory! Where the GAN is easy to turn and corner cut this thing won't move unless it's perfectly aligned. While this may sound like a ding at first (I was initially disappointed) it turned out to be a blessing in disguise! Slowing down and being forced to be deliberate with your turning really makes you think about the moves n helps cement em in your brain for speed solving on a different cube. Definitely a must have!
