The mechanical touch is inimitable, but it is rather noisy compared to conventional membrane keyboards.
This model is 60% of a full keyboard, but has all the functions of key combinations. So you have to master this kind of product. Some keys like "shift" are small. By cons, we have everything at your fingertips, when the Masters.
The backlight is adjustable, default 2 function keys are off but you can turn them on.
The finish is great, comparable to Filco. Only the cable, detachable, could have been better (it is basic), and the document is sometimes absent, which is my case. The latter is in English.
Last thing, this keyboard via OTG adapter on a Samsung Galaxy Tab 3, fully works with circumflex accents and umlauts (if necessary, install the app for physical QWERTY keyboards). Only ASCII shortcuts for Windows accented characters do not work (such as "Alt 144" for "E"). "Ctrl-c" and "Ctrl-V" to copy-paste function. On a Nexus 7, that KBT is incompletely recognized but it is the fault of this tablet with external keyboards.
