if your cube frequently pops, I recommend tensioning instead of complaining not to buy it. Its fast and a very high quality cube for a 12$ 4x4. I highly recommend buying it, but there is a huge issue on how much it pops, so if it does pop, just tension it a little, but besides that I highly recommend it.

First off, I want to say that I am an intermediate solver. I am not the best but I can safely say that this cube is awesome.

Out of the box, this cube was relatively dry. So if you want to get this cube you will also have to get some lube. But after setup, I loved it. Instant main. The feeling is reminiscent of a smaller MGC with comparable corner cutting. Magnets are perfect (though a tad too strong on the inner layers) and it performs well even at tight tensions. It is the standard size as a 3x3 (YS3M pictured) and feels fun to turn. Definitely a great buy!

Mine arrived today and I have been playing with it since I got it. I got this because I wanted something small since I have small hands and wanted something more portable for travel. Out of the box it was fast and smooth. I’m not an accurate turner so I had some lockups and center pieces popping out when I try to turn and don’t align, but I think that I will just have to tighten the cube. Center magnets stronger than outer layer ones. I’m sure once you set up the cube properly, it will be a much better for me. I love how it is the size of a 56mm 3x3 but it is a 4x4. Highly recommended.

The YJ Mini 4x4 is a very decent preforming speedcube, with decent corner cutting, magnet strength, etc, but … DO NOT I repeat DO NOT take this cube apart. As it is nearly impossible to put back together. The pieces are way too small to accurately put back together, and the inner washers are so loose that it’s impossible to keep them correctly positioned on the Bracket. I really enjoy putting together big cubes, like 4x4 to 6x6, but this particular cube is an absolute nightmare to put back together! Get this cube if you don’t plan on taking it apart setting it up or cleaning it, You’ll regret it! I literally had to buy the standard MGC 4x4 as a replacement after I made the mistake 😂😤

Although it has some popping issues at first.. just needed a little tighten and some lubicle 1. Works great now!!

I have pretty normal sized hands, but I felt I would probably enjoy the size matching my 3x3 and my goodness, this cube is fantastic. This is my first 4x4 since ordering a "2x2, 3x3, 4x4" combo pack for $20 dollars off of Amazon, so this is my first magnetic 4x4 made by a name brand and so take my review with a grain of salt. Feels like a great turning puzzle and I do have some pretty premium 3x3s to compare to.

Small down tick because of a couple of defects in the plastic out of the box. I found it a bit distracting during solves so I'm thinking down the road, I may order another one because I do enjoy the cube otherwise.

like many others, i learned... a little too late that this cube is slightly loose out of the box and is prone to popping until you tighten it. this led to me learning how to reassemble a 4x4, which is particularly fiddly and not something i hope to do too often. however, once reassembled and properly tightened, it is an absolute joy to solve! just... be sure to read these warnings and tighten it before use!

The cube is very good but very dry ootb but with lube is bussin

the cube is amazing. i love the feel of the turning better than my other 4x4s (which include gts2m, gan 460, and the valk 4m) it’s not nearly as stable as those. it can be a bit locks with larger cuts but if it’s looser then it can make them. making it looser does make it way more likely to pop though. i love this cube and it’s currently my main. i have around average sized hands (7 1/4”) and it’s really easy to make all the moves i want and small enough where’s it’s really super comfortable to hold and big enough where i can do every turn as well as a normal cube

It's a good 4x4 but it comes really loose out of the box and it really bad until you tighten it.
