Tiled QJ 4x4 and Mefferts 4x4 Are they the same?

[zugohugo2]

I was wondering if mefferts and qj 4x4's are the same. I'm talking about the regular sized qj not the mini. If anyone has a mefferts and a qj could you tell me if the center pieces are the same size? Thanks

You broke one of your center pieces ? Yes, you can use a Mefferts center on a QJ and conversely, they are exactly similar.
