What do you guys think of the periboard 522?

I was browsing amazon the other day, looking up trackballs, and came across the Perixx Periboard 522, which is a 70 percent-ish + numpad + trackball. From what I can tell, this is a relatively new keyboard given the only reviews being from the past couple months, and I can't find anything online about it, except for the amazon page, and the official website. I love the layout, except for that awful 4u spacebar. And, the integrated trackball looks amazing. Additionally, it looks like the cable isn't even detatchable.

Do any of you guys have it? How good quality is the keyboard? Is the trackball good?

I would love to hear your thoughts, since there is no other information online.
