For keyboard:
The quality of the keyboard is just great. Nothing cracks or hacks. All keys go soft as butter and the play / write functions in a comfortable volume level. The keystroke is like a Logitech G15, but the stop level a lot quieter.
The lighting is really the hammer, adjustable and adjustable in color. Here I was really surprised that the illumination in all colors is very clear and evenly. I know that so not of other keyboards. Since one always has regions which, which are better and which bad illuminated.
The keyboard surface I would want to identify with a good grip. It's not really rough, but it's also not a typical gloss coating as with conventional keyboards. Here, the manufacturer Razer has had really come up with something. Even if you come on hot summer days or many games hours sweat, it does not slide over the keys. I'm very pleasantly surprised.
In terms of functionality I have not even be able to try everything and I will not use some of the functions determined. A nice feature, which no longer should nowadays are missing, the programmable macro keys. Without this, I do not want to sit at the computer. Even simple office keyboard shortcuts I use daily (copy, paste, close applications, Show Desktop, or My Computer, etc.)
Feel and quality convince here so across the board. So who can live with a US keyboard, here gets a really good keyboard, in a unique design with a travel range of functions.
