Purchased approximately six months ago with the intention of conducting experiments with it. This model's dimensions instantly drew my attention (of course, I read the attributes first, but the dimensions are still amazing), which, in my opinion, is a positive, given that I prefer a free semi-lying landing at the desktop. The materials are of a high quality, and the brush stand is very comfortable to use, despite its propensity to collect dust and grime. Although the keyboard may be operated without looking at the keys, it took a very long time for me to become used to using it that way. Nevertheless, I'm not used to the position of the F1-F12 keys in this keyboard. In overall, the purchase lives up to all expectations. The benefits of using this keyboard much outweigh any of its drawbacks, the majority of which can be overcome with practice if you so choose. After it was over, I was concerned that I would no longer be able to use a standard keyboard, but I found that there was no dissonance.
