I would love to see a video of a good speedcuber taking an out-of-the-box Rubik's cube and getting sub 30 with it. I'm really new to speedcubing and my best is around 2 minutes with an unmodded Rubik's, but I feel like it more than doubles the time I should be getting (ordered a Zhanchi which hasn't arrived yet). I just don't know how these things can possibly handle fast turns... if there is any misalignment at all, it will simply lock up, and it hurts your hands after a while because of the force you need to do U turns with your finger.
