This is a very rare piece of hardware. A gaming mouse built like this would be the opposite of what's needed. But a keyboard like this is perfect. Unfortunately but necessarily you really have to handle it to understand fully what that means, which is very difficult even in a store. It has a fully cnc-machined 3-part case of some gorgeous modern aluminium alloy with dark anodising and amazing surface texturing. There are as many or more inner layers of metal & dampening foam as the regular Azoth, and an added carbon fibre layer, all supporting/regulating the switch motion. Key-caps as for the Azoth. In the ASUS images, everything you can see besides the key-caps is this aluminium alloy. Everything. The machining is high-end industry, beyond your local cnc-machine shop. The right-side switch and button are also metal and the small screen is now colour. The arm rest is equally supreme with gorgeous dense closed-cell foam and a metal base plate. It's certainly firm as new, but will therefore last years without collapsing. The pair weigh perhaps 7-8 lb. Really. So, enough of the description. This keyboard has unimaginable presence, like an exotic motorcycle, and the key action in typing seems dampened with liquid silk. The Snow switches have no mid-way click, just giving a small to moderate clack at full depression. But there is absolutely zero side motion or wobble. Zero. Function in typing can only be described as gorgeous and perfected vertical motion with beautiful feedback but quiet enough for any environment. Structurally this board will last for generations of your family. Truly and seriously. It's obvious that you could replace switches as often as you could ever want or need and aside from eventually needing a new battery after years, this is a keyboard that would therefore last for generations. This brings up the main and key issue to consider here -- whether you see any tool in life as merely being the cheapest way of getting a job done that will last an OK duration and be pleasant enough to use (buy the regular Azoth) or as an expression of high art, engineering and materials science, in which case this Azoth Extreme is appropriate. Because that's the experience of handling and using this keyboard. It really is a full-on Mercedes S-class of keyboards. That's not hyperbole. This thing is astonishing. And you will be able to replace parts (hot-swap switches etc) at will for at least a couple of your lifetimes, easily. Only switches and of course the battery will eventually wear out. The rest of it won't. So, is it worth slightly less than double the regular Azoth? No. It's worth much more. Really. You HAVE to handle it to know, because you won't believe me here. Then you WILL know.
