As Harris said, this is definitely the best cube I've ever tried. Its movement is very light and frictionless, yet the cube has a "crispy" feel to it at the same time. It cuts corners as well as any other DIY, and I cannot even force a pop if I try. Occasionally the cube locks up a bit because it is fairly loose (even at the tightest screw tension), but other than that, I can see no downsides. For some reason, this only seems to happen to the white cubes, but the black cubes barely ever lock up.
Also, I ordered two black and two white type D DIYs, and I ended up getting 4 different color schemes! The black cubes have pretty crazy schemes (one is white/orange, red/blue, green/yellow). One of the white cubes has the normal color scheme, and the other has the normal color scheme with white and yellow swapped. However, I should be receiving some replacement some stickers from Cubesmith shortly, so this isn't a problem.
Overall I rate this cube (type D) as the best DIY out of the four Chinese types. I'll try to make and upload a video later tonight.
My new white ES cubes might make an appearance in the video as well
