Please note that some new cubes when being used for the first few times may experience what is termed a "pop". This is when one or more parts of a puzzle pop out without any damage actually being done to any of the pieces. This also occurs from time to time during normal usage. Pops are typically not considered a defect if the parts which come off can be reassembled by hand.

Great cube

A great overall cube. My favorite part is the size. it's the perfect size to do regular 3x3 finger tricks

Came with a rattling corner piece.

The cube had a corner piece that was rattling out of the box. Otherwise the mgc 4x4 was really nice once you loosen it a bit (it comes a bit tight in my opinion). The reason it’s a 4 star is because I contacted Cubicle customer service and I got a replacement corner piece ASAP.

Great Quality for a Good Price

You can customize the cube to be fast or controllable. This is a great option for anyone who is looking for a good 4x4 for a good price.


I now have every MGC big cube and all of them are crisp, fast, and perform excellently

Great cube

It is a great cube well I recommend to tighten the cube before you spam turns on it

Great Cube for a Reasonable Price!

Great cube! Just like the 6x6, and 5x5, but the reason I gave it 4 stars instead of 5 like I did for the 5x5, is because their are better 4x4's out there, and it is about the same price as the 5x5. I think this is a great cube, but I feel like it would also be a lot more noticed if it was cheaper. Overpriced in my opinion.

Great 4x4

Fairly stable cube, pops occur but are uncommon
The good kind of crunchy
Layers stay together well when doing 3x3 algs
Good contrast between colors (stickerless)

Not Bad

Was a great cube when turning, but was extremely vulnerable to popping.


Simply superb 4x4. It will not hinder you in any way; it is just as useable as any other flagship, and far cheaper.

Dry OotB but gets better immediately. I don't setup my cubes until I've broken them in a bit and for me at least the problem fixed itself, I only had to re-lube about a week and a bit in. People tend to go overboard with their setups as soon as they get their cubes for some reason, I encourage you to allow the cube to come into itself a bit before you drown it in lube. You can't break it in properly when it's coated in Silk and Martian and all the other things you guys bathe the plastic in.

Tensions were fine OotB. Inner pieces pop occasionally but not often enough to be a problem. Have never experienced any unusually persistent lock-ups myself, I assume those that have are operating on a far looser setting. Cube comes with two sets of spare springs: stronger and weaker. I've tried them all and prefer the ones it comes with.

Inner layer magnets are stronger than outer layer ones, which makes those double-M slices super easy. Spare magnets are included of both strengths, though not many.

Size is fine, and the cube is quite light, which is nice. I will never understand the mindset that a 1mm size difference is at all significant, as I can achieve my average (sub-40) no matter the cube size, but some people do, and I guess that's down to hand size. If you have smaller hands, are an elite, high-level competitor, and are hypercritical about your hardware, *maybe* consider buying a different cube. If not, I wouldn't worry about it.

I bought both stickered and stickerless versions to test them out. No noticeable difference in terms of feel. Sticker shades are fine, I struggle to tell apart red and orange usually, but had no complaints here.

Overall, if you're thinking about buying your first decent 4x4, buy this one. If you're reading cubicle reviews to inform your decision, that's of course fine, but you probably don't need a more expensive puzzle than this. A five-star cube with no significant drawbacks that can be customised significantly to your liking. It's perfect for improvement, and perfect for getting yourself hooked on the event.
