OOTB, the cube was extremely tight, and I personally thought the cube was going to be way too tight for my turning style. Also, the feeling was smooth, slow, and a little clacky. After about 10 break-in solves, the cube is still slow, but faster than it was, making it more of a controllable feeling than slow. Plus, I did not loosen the cube because the controllability kind of forced me to adapt my turning style, so there is now no catching at all. After 20 break-in solves the outer layers are really speedy and a very similar feeling to a well-lubricated GTS3. The inner layers are about the speed of the outers when I first got the cube. Mystic is known for its smoothness that it provides the puzzle and it shows through here. The cube now is practically frictionless. The outers are just like turning a 3x3. If I had to compare the feeling, It is like a Valk Power with lots of Silk in it. This 3x3 feeling will obviously benefit 3x3 stage and my last layer is really fluid. If there is any catching, it's during use of the inner layers, but that is due to the tightness of the cube. I have now well adapted to the cube as it is my new main over my Wuque M.

turns super smooth and fast, outer layers turn like a 3x3 and wide layers turn like a 2x2

I love this puzzle! It is very smooth, with strong internal magnets that give a smooth and somewhat crunchy feeling. 3x3 stage is also a dream on this puzzle, being very smooth and fast. I would highly recommend this puzzle to anyone looking for a new 4x4!

It’s better than any 4x4 I had previously, but not as good as I was expecting for the price. Then again, at least for me, any even layered cube isn’t as good as odd layers, so I guess after this that’s probably unavoidable. I would highly recommend this 4x4 if it was $35

Simply put this is the absolute best 4x4 on the market as of June 2020. The outer layers are just insane, buttery and fast. The inner layers are slightly gummy at first but after a few solves it is just perfect. It is expensive but if your looking for the best 4x4 this is it.

this is my first 4x4, but I have 8 3x3s to compare to. The 4x4 outer layers are probably as fast as a yuxin little magic, but a lot more stable. The inner layers are my only problem though. They are extremely slow and maybe I j just need to break-in. Since I think the inner layers will improve, I will leave it as 5 stars, looking forward to a new event :).

I ordered this so I’d have a better 4x4 for a comp I’m going to soon, and I also wanted to get faster so I could make cutoff. The only 4x4 I’ve had since 2017 was the Mini Aosu, so I knew this cube was going to be a lot better anyway. My order came today, and right out of the box it was my main. It’s so smooth, accurate, and fast while still being controllable. I decided to do a few solves to see if it improves my times, and they dropped by an entire minute and a half (consistently)! Now I’m just a few seconds away from making cutoff and averaging lower than I ever have before. If you have the money and have any interest in 4x4 whatsoever, buy this cube! Totally worth it.

I have a stock, Pro Shop, and now a Mystic Aosu. The best one without a doubt is the Mystic version. I have no complaints about the others but because of the slightly slower inner layers it makes the yau stage of my solves even more consistent. I mow hold my PB of 41.020 on this cube; it would have been in the thirty second range had I not dropped it. I currently swap between the Mystic and the Pro Shop version as my main. This is a whole-hearted recommendation.

I have but one complaint, and it barely is able to be called that, and it is that the inner layer magnets seem to be stronger than the outer layer, making it feel slightly sticky. However, I still love the cube, and it has become my favorite out of my collection, other than my first cube.

Even though I don't have any other good 4x4 to compare it to, this cube is a little slow ootb. It was kind of like an mf3rs2m but a 4x4. Then, I did a couple solves and right away it got fast and super smooth. I do have some problems with it, though. Even though these problems aren't the cubicle's fault, I think that I'll include them in here. When on looser tensions, the corner cutting is okay but the inside pieces pop a lot. Due to my more inaccurately turning style, I don't think this is the best cube for me. It's still great, though and anyone who needs a good 4x4 that's setup professionally should get this.
