Keyboard:
First, it is a full-size keyboard, so no mini buttons. The layout must always look for themselves, I have not soo big claims. The Ctrl key is outside (not Fn), which is actually the most important thing.
Typing feels very very good, the keyboard has a flat writing stroke with a clean stop and I can use it very fluently.
Bonus point: The buttons can be backlit, ideal if you're sitting in the dark and would like to briefly touch something.
Touchpad:
The touchpad gives me great pleasure. I use a Macbook Pro and am very enthusiastic about the touchpad, and this has the same gestures (right-click with 2 fingers tapping, scrolling with 2 fingers pull, front-back with 3 fingers to the left and right, etc.). The only minor negative point are the areas below for the left and right buttons. This would not be necessary due to the gesture and they make it difficult to use if you accidentally end up there, right-click triggers in any case want to. But that's getting used to things. The touchpad feels nice, not too rough, not smooth. What is completely missing is a haptic feedback for clicks.
Reception:
Perfect. I had as yet no dropouts. I hope it stays that way (I once had such a keyboard that was three weeks great and then getting worse, no matter what I was doing).
Housing:
The housing is mostly (if not completely) from aluminum and feels very stable and of high quality. It is torsionally very stiff and I was not afraid when it is sailing times from the sofa.
Upload:
The keyboard can be loaded, which is nice in itself, but unfortunately whimpers this very intrusive with high irregular tones exclusively via the included Induktionsfeldchen. Can only download overnight, actually, when no one is in the room, otherwise you turn through. Moreover, I find it alarming that there is no alternative to a microUSB input would be nice. Furthermore, the induction field must be connected to a PC. This means that if you load overnight, also one must be turned on. A power supply as would be nice. Whether you can connect the charger to a smart phone charger, I have not tried it yet, but think so.
Overall, I highly recommend this keyboard completely. I'll try to supplement (if need be) by a few months again.
