My initial impressions of the board are positive. It uses some kind of flat blue key switches, I am not sure what kind.
Typing feels like you would expect, although I have some issues feeling the correct actuation point. As a result I tend to bottom out a lot. The click sound is loud enough for me. I would not bring it to a library.
The design of the board is above expectation. I like the industrial build with the dark grey metal plate, it fits well with my aluminium MacBook Pro or iPad. It has a decent weight, which gives it a premium experience carrying it.
Features wise it is a bit of a mixed bag. The USP they promoted most was the dedicated Siri/Cortana key. But it does not support iOS/Android! The bluetooth connection is stable and supports up to three devices. the RGB backlighting is nice but not used much. I enjoy the dedicated media keys, which are supported by MacOS and iOS, especially the media keys are useful.
The board was 75 euros for the board itself, but they forgot to add around 30 euros import fees. So in total it came to 105 euros, which comes down to 120 dollars.
