Two words; the best. Super smooth, fast turning, great corner cutting. Totally worth the money.

I've never tried the valk 5 before getting it, and it lived up to every expectation I had for it. It is fast, controllable, light, smooth, and overall an amazing cube. It feels like the X-man Shadow M, only faster and less bumpy. Get this if you are into 5x5 at all! I beat my PB shortly after getting it, (1:13.366), and, overall, my times are better than when I used the AoChuang GTS M. Would recommend 100/10!

Out of the box, it comes tight, greasy, and dry. But after break in; it's fast and smooth. It has minor catching and lock ups but they're easy to fix. The magnets aren't too strong and are hard to notice when turning pretty fast. The shades are the same as the Spark M 7x7. I have no doubt this will become a main for a lot of people.
