Pretty easy once you learn the main few algorithms, they just become muscle memory like anything and no longer exist as a set of steps. Got down to around 1m 15s, I've forgotten twice after a long gap of not doing it, but a quick brush up and it all just comes back. I really should push myself and expand beyond the basic algos though.
I learned on a standard official cube but then I got a proper cube with all the adjustable gears and magnets; and it was night and day, so slick:
GAN 356 X Numerical IPG 3X3 Stickerless Magnetic Speed Cube (V1)
The official cube is absolutely hideous, they're so stiff, grindy and awkward.
One weird thing I notice after spending more than 10 mins or so with it, is everything I touch afterwards feels rounder...
