This puzzle is amazing and probably the best on the market get this cube. Now my full review, this cube is extremely fast on all layers and extremely smooth, the stock lube and tensions were great and out of the box I did an initial Ao50 to test it out and I broke all my PB's except single. The feeling is really hard to describe, its really smooth with the slightest hint of a sandy crunchy feel, it's very subtle. Corner cutting is decent, forward is about a piece, a little less and reverse is a little less than half a piece, this applies to all layers. Despite the mediocre corner cutting(compared to cubes like the SS and MoYu) it doesn't lock up much, though it does get the same bad lockups as the AoChuang, but it's not too common. Stickers are the same as what you find on MoYu cubes and are high quality. Personally I think this is the best 5x5 on the market and it is great out of the box and doesn't need lube, so no work is really needed. All in all it's an amazing cube for a great price that I highly recommend.
