I agree with everybody here; the FII is not only superior to the Diansheng (Doesn't matter which model it is), but as well as a lot of other cubes. It compares well with the A5 which is basically the GuHong's Rival since it never pops and/or lock up. It also cuts corners generally well. If you really want both the Diansheng and the FII, go ahead, it is only $3-4 more. A good thing about the Diansheng is that it is comparable with a semi broken in Rubik's storebought and it is very good as a present for a friend or for a backup cube (You can leave it in your bag in case you forget your main cube or when a friend wants to try your cube)
