If anyone has some Gan cubes or magnetic cubes and preferably lives in AU/NZ/Pacific Islands for less than US$20, I would like to purchase some. If you want to trade, I have some 6x6's and 4x4's I don't really want. If you want a QiYi Pentacle Cube for $10, I've got one.
I once tried to teach about half of my class how to solve a cube. About 3 of them got the first layer and cross and stuff, but the other 12 got stuck. I know a guy who is top in the country for chess, but he can't grasp the cross. Some are talented in this field, others just aren't.
