Hi,
I just received my 4x4 QiYi Wuque and unfortunately it popped into one hundred pieces after the very first solve. I can't setup it perfectly because 1-2 layers were un-turnable. Tried it many times but I can't do it right... I had to drop the cube although I was waiting for a 4x4 for almost 6 months. I would like to buy an another one but I'm afraid of popping because I would not be able to setup again...
Which speed-cube is the best for me? Or every 4x4 is as difficult to assembly as Wuques?
