I ordered a square-1 from rubikfans.com about a year ago, it came in a QJ box. However, I recently removed a middle cap, the cap hiding the screw, and the inside of the cap said mf8. Does anyone know whether or not this is a QJ or mf8 square-1? I lubed it, and it's too slippery and could +2 easily, and I wanted to order another mf8 square-1, but if it's going to be the same then I don't want to order it...
