I got a diansheng 10x10 with primary internals. It turns extremely well, in comparison to my meilong 9x9. Inside the box (new version) you get pull-out 2 shelves. On the top shelf you get the cube, and on the bottom you get accessories: cloth, screwdriver, stand, and giant cube bag(i was able to fit the 10x10, a pyraminx, a 2x2 with no problem at the same time). The box is nice and magnetic and not worth throwing away.
Lets look at the cube. The cube is around 75 millimeters, and feels very easy to turn all layers on demand, although the middle layers are quite hard to turn, otherwithse, the 3x3 layers are amazing, and after break in, i was able to do the M U h perm with finger tricks. The 10x10 feels quite smooth, a big improvement over the cheap feel of the meilong series. The layers after break in feel almost the same. The magnets are the difference of a lifetime, though, which is one of the reasons to buy this 10x10.
The cube hardly ever pops, so no problems with that.
The cube is quite easy to hold with a glossy finish, and small. The plastic overall feels amazing and doesnt feel like a budget brand(because it isnt). The color shades are rich and dark and look better then colors on a meilong or other brands, the outer layer is slightly concaved, which, in my opinion adds to the feel of the premiumness.
In conclusion, this cube is a must have in the collection of anyone who likes big cubes, since non magnetic big cubes turn that audience away. I hope my review helps.
