So yesterday, my friend and I traded puzzles for the evening: I use the Wuji, and he uses the MGC.
Here is a brief review on my thoughts about the Qiyi Wuji (so far from me struggling to get good times on the puzzle)
The puzzle is really unstable. I cannot do a single T-Perm without the puzzle locking up on me.
The puzzle is really hard to tension. I just cannot find a setting that works for the puzzle. Too loose, it is unstable. Too tight, the puzzle loses is fluidity in the slices.
The puzzle has some great slice turns.
The price is 90 dollars when it was in stock at TC, making it extremely overpriced.
And my thoughts on the MGC (which I had gotten during the summer):
This puzzle is a lot more stable than the wuiji, making it easier to speedsolve.
Cornercutting is decent, and I am able to get a speed that I like.
Tensions are better.
AND the price is 35.
That's all I can say about the Wuji. It is an overpriced heap of junk, IMO. I know this cube was used to break the world record even before it was released onto the market, but the MGC is just better in turning, more stable, and blockier too, making it look nicer. Even my friend agreed that the MGC was better than the Wuji
