I really enjoy solving giant cubes, it just feels good turning them fast, giving my arms some excercise while also practicing my all angle F2L solving and efficiency. I was very pleased when QiYi first leaked their even bigger 3x3 back in October, I even tried to work out its size by the height of a guy solving it blindfolded. Now I finally have one and I can now also say with some confidence that I probably have Unofficial world record, if anyone disputes that then update the list of UWRs. I don't currently stock these, if I did then it would probably be twice the price of the DianSheng 35CM cube.
