Razer's BlackWidow Ultimate is something of a novelty, if for no other reason than Razer builds it with keyswitches of its own design, where the rest of the industry uses Cherry MX switches of one form or another. In a press release, Razer claims some cred for the switches, saying they were "tested extensively by the world's most demanding eSports atheletes, who validated the new Razer Mechanical Switch in some of the most intense professional gaming tournaments."
Razer actually designed two types of mechanical switches, the Razer Green and the Razer Orange. The Razer Green switches in the BlackWidow Ultimate feel very similar to Cherry MX Blues. They require the same actuation force--a fairly heavy 50cN--and they exhibit the same "clicky" tactile feedback. (cN, if you're not familiar with the term, is an abbreviation for "centinewton," a unit of measure for force.) The Razer Greens, however, have a much higher actuation point. It's very close to the keycap's resting point, and its resistance fades rapidly past the actuation point.
In fact, the high actuation point and initial resistance make the Razer Greens feel a bit like a clicky rubber-dome switch. Touch typists love Cherry Blues because you can learn to strike each key without ever bottoming out--your fingers recognize the actuation point and pull back. The Razer Greens' actuation point comes so early, and its resistance beyond that is so minimal, that it's difficult not to bottom out on every stroke.
To be fair, Razer says up-front that this keyboard is designed specifically for gaming. And for that, the BlackWidow Ultimate's high actuation point is great. It allows you to double- or triple-tap keys quickly, much as you can with Cherry Blacks. But instead of that switch's linear resistance, you get the the clicky, tactile feedback of a Cherry Blue.
As for the rest of its design, the BlackWidow Ultimate features Razer's standard black-and-neon-green color scheme. Keys are individually backlit, with settings that range from "off" to "pleasant, soft green" to "eye-searing, radioactive pain" (those are my characterizations, of course, not Razer's). But hey, if you're ever using the BlackWidow Ultimate on the surface of the sun, you'll still be able to see its backlight.
There's a column of five macro keys on the left side of the board, which you program using Razer's Synapse software. All settings are stored in a personal profile in the cloud instead of on-board memory. This means you must register an email address with Razer and install Razer's Synapse software on every computer that you attach to the keyboard.
The top row of function keys have secondary functions, activated by holding down a second key. There are the usual media-player control keys, a Game Mode key, a key for on-the-fly macro recording, one for adjusting backlight brightness, and one to put your computer into sleep mode. The keycap that activates these secondary functions is not backlit. Because it's the only key that isn't, however, it's relatively easy to find.
