Something I've noticed is that beginners tend to get one of the lower tier 2x2s such as the LanLan (or V-Cube or Ghosthand) to start for some reason. I think a general rule is, if there are no Florian cuts, it's not a great 2x2. I think it's not worth it to buy any of these 2x2s; you're better off buying a LingPo, TangPo, DaYan, or one of the FangShi or WitEden 2x2s (I'm sure I missed some, but the DaYan's really the best 2x2 anyway).
