It's got four rubber feet for traction and standard flip-out elevators for adjusting the typing angle. Keys are held in place firmly and don't rattle around. The combination of matte and glossy black plastic doesn't look half bad, and the entire keyboard feels very well built. It'll feel so good you'll think you lost your virginity.
However, the Model S Professional makes up for that the moment you press your first key. Razer is the only one that did a good job designing the exterior to look a bit more like keyboards you'd by only because they look good. As far as mechanical keyboard go, they're a bunch of somewhat ugly chunks of bulky black keyboards. Not to sugar coat it, the Model S Professional isn't going to win any awards for its beauty.
That means the blue class offers the most audible clicking sound and feedback possible. Mind you those are Cherry MX blue mechanical key switches. Compared to others though, its got only the best internals like German-engineered mechanical key switches that are gold plated. In essence, the Model S Professional is a plain and simple keyboard by the looks of it. I'm no mechanical keyboard expert, but $133 is a bit too much for what you're getting.
