Summary: I got the mouse as well 79158 for Roccat talk effect. Not worth buying for the effect as they seams to be glowing off sink most of the time. Have to download the drivers from website. Macro cap locks, num lock button are always blue and can not follow other key color change. You can not custom change any single key or region of the keyboard. You can assign macro to the ASD region.
Pros: macro, quick key, and functions key on top of keyboard.
Cons: Color breath switch dry, not as smooth as expected. ROCCAT talk out of sink with mouse.
Summary: Purchased same model before for a PC build and love the keyboard. If I have any slight issues, it is simply that you cannot change the key colour background to match the Roccat Kone Pure mouse. It's blue or nothing (mouse has multiple colour choices). This is simply a design choice and has nothing to do with the excellent operation and programming of the keyboard. Highly recommended.
Summary: The Goods - Key lighting is great - Comfortable to get used to - Good tactile feedback from the keys - Fantastic customization and settings - A++ Build quality and feel Roccat has done a great job on the feel of this keyboard. Although it isn't mechanical, it is defiantly at the top of the list of the non-mechanical list. the key-press is super responsive, comfortable to use and well set out. Whilst gaming there was no lag, ghosting or sticky keys.
Summary: Been using this keyboard for 6 months solid now, wont be considering getting a new one for a long while! Design/Build quality: The keyboard is made of plastic, but then again, so is practically all other keyboards that arent stupidly expensive. It looks phenomenal! Cant fault the looks at all! As for actually build quality, cant fault it there either.
Summary: Great keyboard that compliments roccat's other accessories well. Lighting is good and makes everything very clear in lowlight. Responsiveness is spot on....if I have one minor niggle....its fact the keys make bit too much noise, but that's it.
