Nice keyboard, good features, but cheaply built and no KVM support.
on May 30, 2015
I wanted to like this more than I do. I tend to work a lot in the dark, as I hate reflections on my monitors when I'm doing color work. That makes using a keyboard a bit tricky at times, so I finally got an illuminated one.
With this one, I can set custom colors & effects for 5 different apps/games, easily with the driver software. However, since this is a non-standard feature, it doesn't play nice with KVM switches. If I plug this into the keyboard port on a KVM, the keyboard works, but I lose the extra features like the application detection or custom keys. If I plug it into the KVM's USB hub, I get all that back, but then I lose the hot-key switching ability; it's an either-or situation. I contacted Roccat and they don't have a solution for this and do not support KVMs. If you're only using it on a single computer, then you're set; the features work great.
As for the keyboard itself, it does feel a bit cheap, unlike Roccat's mice, which feel great. It has an enormous wrist rest on the front, which I find very annoying; I prefer the space bar to be only an inch or two from the front edge so I can keep the keyboard closer to the edge of the desk, but with this, even with if overhanging the edge of the desk, the keys are still about three inches further away. The wrist rest is also not cushioned in any way; it's a rough textures styrene plastic, and it's not removable; it's the same piece as the entire top of the keyboard casing. It's not rounded, and those angles you see in the photos are pretty sharp, and my forearms are already getting irritated by them.
The keys are also on the cheap side. I've been using a Logitech wireless keyboard for the past 13 years, and while its keys are not the mechanical grails they could be (they press against a membrane inside), they do move quite nice. The Isku keys feel more like what you'd find on a toy keyboard, and are not ergonomic in any way; there's no curve difference between rows, so every key feels the same, except the F and the J. This is not a keyboard for writing, and without the curved tops (these key tops are all perfectly aligned with one another, making the keyboard very flat), I don't see how this would be a great gaming keyboard either. I'm a bit ticked that a keyboard in this price range has such cheap keys, when a $20 (or less) Logitech has such better keys.
After a couple weeks with this, even though it's a nice looking keyboard, I'm starting to wish I went with their next model up which uses Cherry keys (arguably, the best keys you can get), or a more basic, illuminated keyboard like the Deck (which also uses Cherry keys).
I got this based on my experience with their Kone mouse, which is a really nice mouse (but apparently also has KVM trouble).
