When is a Wireless keyboard + full-size backlit alu + +?

I looked everywhere wireless keyboard (like this one), with a numeric keypad and directional arrows (like this one), aluminum (or at least dull (not shiny as keyboard) and backlit (not like this one, but it compensates with the fact of never needing to be recharged)

Well, such a key does not exist. The aluminum or matt keyboards seem virtually reserved for Mac (this is not an absolute rule, but it is often true; for example, the Mac version of the K750 is matte silver plastic); Alus the wireless keyboards are wired, if they become wireless lose their keypad ... Etc.

So in desperation, I fell back on the keyboard.

I will be brief and concise: it is perfectly for which it is announced. For one, it has never dropped below 100% battery. By cons, it takes fingerprints, and it is not backlit ...
