The Dayan LingYun is the third version of the Dayan 3x3 speedcube. Currently they only sell the second version of the LingYun, which just has added torpedoes, which makes it much better. Torpedoes are an added part of an edge piece that hooks under the corners to prevent pops. The Dayan LingYun is a very fast, crunchy, and snappy cube that requires a very light turning style. If you break it in, the crunchiness diminishes but doesn't go away.
The stickers that come on it are badly placed and a little dull, so I recommend replacing them with shades that you prefer. The mechanism is like a combination of the Dayan GuHong and the Dayan LunHui cubes, which makes sense as the GuHong is the second version of the Dayan 3x3, the LingYun is the 3rd version, and the LunHui is the 4th version. Taking a close look at the edges reveals the reason behind the crunchy feel: there are indents on them that are against the direction of turning, causing some friction that makes the turning feel crunchy.
Corner cutting is a little over 45 degrees, and almost line-to-line reverse cutting. This excellent corner cutting is caused by the very shallow scoops on the corners, and the space between the edge and corner that allows the cube to flex a lot while corner cutting. Although the corner cutting is on par with other modern speed-cubes, this corner cutting takes a little more force to accomplish than on many other cubes, so the cube still catches a little during solves. However, this isn't much of a problem.
One thing to note is that the center caps are extremely hard to get off of the center pieces, and they are not quite flush with the edge of the centers. The edges and corners are also extremely hard to get apart, but this is not as big of a problem as the center caps unless you want to do some internal modifications to the pieces.
I would give this cube 4 stars out of 5.
