I'm going to order a 2x2, and I want a good one for speedcubing, but not to expensive. Should I get the YJ or Diansheng? Or is it worth a lot to add 1$ and get the Ghost Hand or LanLan? Just want a fast 2x2 that doesn't pop a lot. And with decent corner cutting, but most importantly, it should be worth the money, so I think one of those four.
