Hey yesterday I got my new Mefferts megaminx in the mail, and right out of the box, turning quality was horrible. Also it pops very easily, and I do not know what the problem is. I have lubricated it and the turning became somewhat better, but I cannot stop it from popping on me. I have also tried tightening the screws, but that wont stop the pops either! This is driving me nuts! Can some one please give me a suggestion on what I should do about this?
