Customers praised this 4x4 cube as "extremely smooth with excellent corner cutting" and "the best 4x4" they've used. Most noted it requires break-in (5-10 minutes) but becomes "perfect" after. Reviewers loved the fast turning, stability, and that it rarely pops. Some found it overly lubed initially or arrived tight. A few mentioned price concerns and sticker durability issues.

My first 4x4 after not practicing for 3 years. Fast and and amazing after break in!
I had an excellent experience ordering my Mgc 4x4 from SpeedCubeShop. The ordering process was smooth and straightforward, with detailed product information that made it easy to choose the right cube. I also appreciate the setup options and clear descriptions, which show how much SpeedCubeShop understands cubers’ needs.
My order shipped very quickly and arrived sooner than expected. The cube was packaged securely and arrived in perfect condition. Right out of the box, the Mgc 4x4 felt amazing—smooth, fast, and very controllable. It was clear that care was taken in the setup, as the cube didn’t require any immediate adjustments to perform well.
Performance-wise, this Mgc 4x4 really stands out. The turning is extremely smooth with excellent corner cutting and minimal catching, even during fast solves. The layers stay well-aligned, and the cube feels stable without being too tight. It handles both fast turning and precise finger tricks very well, which is especially important on a 4x4.
Overall, I’m very impressed with both the Mgc 4x4 and SpeedCubeShop’s service. Between the fast shipping, great packaging, and high-quality setup, this was a fantastic purchase. SpeedCubeShop continues to be my go-to cubing store, and I would highly recommend them to anyone looking for reliable cubes and excellent customer service. I’ll definitely be ordering from them again.
It used to be my main. Great price!
Love how it feels. AMAZING!
It's a good cube with smooth turning, and I would recommend it to someone who wants that.
Hope you can read chinese
Really smooth after break in
Started a little slow of course but once it breaks in its really nice to turn
Feels great to use, very smooth, and it's my first 4x4 so it's very special to me
The cube is great, it’s very nice and has not popped on me even after losing it and it so fast 100% recommend
Cube was extraordinary! the only problem is the price. Jperm just set up the $20 yj mgc cube with his tensioning and his lube. Honestly, lube is only 5 bucks and you could just by a logo sticker online. Other than, I loved the cube and I still use Discount code JPERM.
Good
This is such a great 4x4 cube. It is breaking in very nicely, moves and feels great. Very happy with the product and price.
When it arrived it had little to no flex and tons of friction, I did a little over a full turn on all of the screws to loosen the cube and then it was amazing. I would give it five stars, but part of me doesn’t thinks jperm wouldn’t set it up as tight as it came. And of course the whole point is that it comes set up for you
Very good broke all my pbs but the sticker fell of to easily
I got my pb in one solve and I still have not beaten it
Out of the box the cube was very oily but it is a good cube.
This is by far the best cube I've ever used. It does come with a lot of lube out of the box but I'd rather have too much then not enough
I have had a lot of 4x4 and this one is the best. It takes a little while to break in but after that is perfect. The only thing I don’t like is how much lube there is on the cube when you open it. I used a Clorox wipe to remove some of this lube and it helped a lot.
After 2 days it starts to get sandy and I have no lube to get rid of it
This is the PERFECT 4x4 I would EASILY recommend this cube to ANYONE. THIS IS THE PERFECT 4X4 HANDS DOWN!
At the beginning it was nice but there was too much lub but after 5-10 minutes it was really good
Good cube and is worth the price.
This is the best 4x4 highly recommend
This is amazing out of the box it just needs some break but after that, it is the best. My last 4x4 broke and is unusable this 4x4 feels fantastic and way better than my last one, definitely worth the price(:
This is a really good cube. It comes a little Luby and slow out of the box but after some break in it’s perfect. The j perm logo is 👌
Awesome cube. Only took around 7 minutes to break in. Way better than my old main, the gan 460. The gan 460 kept popping and the outer layers turned so good but the inner layers were bad. I started turning it and it exploded in my face. The mgc is way better and now I love 4x4 because of it. I would definitely recommend this to any cuber. Plus it comes with a Jperm logo and Jperm is my favorite YouTube channel.
I was scrolling down in my YouTube recommended and then I saw the new J Perm video, I watched it and instantly was like "I need to get the 3x3 and 4x4" so I did. This is only my 2nd 4x4 but the 1st kept on popping so I had to rebuy it like 4 times. then I gave up and left cubing. Now I'm back at cubing and I feel like anyone would like this 4x4 advanced or beginner. Thank you J Perm!
