Yj mgc 4x4

Thank you this cube is really good I got so many good solves and you guys are so kind


So I got this cube for my birthday (hence no verified purchase) OOTB it was dry and kinda stiff, Just lube it and then it will be amazing. It has been my main for over 4 months and i don't see me switching anytime soon. I have tried the Valk 4 and AoSu GTS2M and this cube beats both of them. The size is also just right. Overall you cant go wrong with this cube.

Amazing For The Price

I just got this 4x4 a few days ago and it felt tight out of the box. It only took about 1/4 turn on each side to feel right for me. After that i started getting my average quite quickly.
It has a lighter turning style than the Wuque, and its a bit faster too.

Main After Set Up

OOTB, its very dry, but after setup and break in, the cube has become my main.
Would not reccomend to beginners if you can't set up a 4x4. If this is you get the Qiyi MS 4x4.


YJ MGC 4x4


This is my first magnetic 4x4, so don't take this review too seriously if you are a seasoned 4x4 solver. OOTB, the cube was factory lubed but still felt dry and was a little loose. After lubing the core with Weight 5 and the outers with a light piece lube and tightening the cube a bit, it was amazing! The cube itself is a good weight and size for me, and I have been enjoying it so far. The only con is that corner-cutting isn't incredible and it may pop when turning aggressively. I would think twice before buying this cube if you are a super aggressive turner, but other than that it's great!


This is a great cube, it is really smooth and fast. Out of the box it was really uncontrollable and felt like it was going to pop, after tightening the screws, it got a lot better. The corner cutting is not as good as I have seen in reviews though, but it's okay for me because I'm a pretty accurate turner. Also the inner layer magnets are really strong on mine but I got used to it quickly. Overall, I think this is a great cube especially for the price, for cubes who want a fast and smooth 4x4.

Great Budget Cube

This is a great entry into the magnetic cube market.
