I'm really frustrated with the 4x4x4 cube. I've owned 4 different ones including eastsheen, mefferts, maru, and now x-cube. My x-cube is definitely the best one so far, and I've got it broken in pretty well, but I just find it really difficult to actually turn it how I would like.
When I watch videos of good cubers, they just seem to be solving the cube effortlessly, like it just glides in their fingers. I spent yesterday finally learning the parity algorithms, and it currently takes me about 11 seconds on average to perform the OLL parity.
Is turning the 4x4 something that you just have to get used to, and I will get better at it? or am I somehow just doing something wrong?
