Well, I wanted to buy a mini QJ 4x4 but my dad said no because they are probably made in china, that they are probably cheap, and shipping and handling will make it extremely expensive. I kept telling him that the site I'm buying from has free shipping and handling, and that they are the higher quality cubes if you compare them to the regular Rubik's. My dad still refused and so now we have to go to Kmart and buy a regular Rubik's 4x4 for 20 dollars, versus the 8 dollar QJ. Once I get the Rubik's, how can I make it smoother, faster, and better? People said silicon spray works but I only have silicon gel goo thing stuff. Would that work?
