so, right of the bad, it really needs to be tightened. After you tighten it, it is really really good. I got mine for like $14 from cube depot. When I first started cubing in like 2009, a magnetic 7x7 was not even an idea, let alone on for $14. If you are slower than 5 minutes on 7x7, get this cube, break it in, you won't be disappointed.

$14 for a 7x7? This is my first 7x7 and it feels better than several other 4x4 and 5x5s I have for much less in some cases! I absolutely love this cube.

This is an overall great cube! and amazing for the price.

This is an amazing cube! This is my first 7x7 and it definitely exceeded my expectations. The magnets work great, it's smooth and quiet, and definitely worth the price. The only problem I've had with it was that it was a little greasy after I opened it, but now it's fine. Other than that, I would definitely recommend this cube!

As a 2-month-old newb cuber, this is my first venture past 4&5x5.
Like it's little brother the YJ Yulong V2M 3x3, the YuFu has a nice
nice smooth feel to the tiles, shiny and polished. Out of the box,
the cube was quite sandy and tight, but with a few drops of 6wt
in the corners *and over 49 minutes of brain-straining agony* I
had my first 7x7 solve and the cube has only gotten nicer to handle
ever since. After over a dozen solves I really appreciate how the magnets
help keep things in the right place while I am trying hard to excel ;)
A nice touch on YJ's part the inner layers' magnets are stronger and
the outer layers' are weaker, making the 3x3 stage so much easier.

This is the first 7x7 I have ever had, and it seems excellent. It is fast, all the layers turn really well, and corner cutting is good. Stickerless shades are very vibrant.

I don't even know where to start with this review. The cube is very good, and the 69mm size is actually pretty nice, and it feels just as good in my hands as the hays. The puzzle has very smooth and bubbly turning, especially in the inner layers. If you have tried the yj 5x5 it does a very good job of mimicking that feel. The magnets have a nice click, and I would not call them strong, however they are pretty much perfect. The problems I have came when I got the puzzle. First of all cube depot shipped my package to the wrong house, which is understandable because cube depot is in new york not area 51, so I know they are all humans and they all make mistakes sometimes. Luckily I was still able to get the package, and get all the cubes. OOTB this cube was horrible. The cube was soaked in lube like the dayan tengyun and it was very loose, and I felt like it almost popped several times during the parity alg. So because I really wanted to give this cube a chance, I took the whole cube apart, and cleaned out all the pieces and lubed the core with traxxas. I started to reassemble the cube, and as I was assembling the final face one of the very outer corners in the center snapped. This really surpised me because I was not putting much force, and I have never had this problem before. So I did the only thing I could think to do at the time which was to superglue the broken piece back together. This solution was fine, and I was able to reassemble the cube, however because of the way the glue cured there is a slight bump on that corner where the piece jutts out just a little bit. This gets in the way while solving, but luckily on 7x7 I only really have to touch that specific piece a few times. I am very frustrated with this even though I think this a great puzzle. All in all I reccomend this to anybody starting 7x7, but be very gentle with it if you take it apart or pop it because it is obviously very prone to breaking. For 14 bucks I don't think you can go wrong with this.
