1. Extremely inconvenient location of all system keys (shift, enter, /, backspace, insert - everything is terrible).
2. The compactness of many keys completely deprives the keyboard of any ergonomics (in particular, Enter, Del, ↑ are too small), it would also seem that due to the compactness of the entire keyboard, it should be intended for a sofa, but the rounding of the keys makes it difficult to find on a soft surface (accidental pressing).
3. Separately, it is worth mentioning the narrow up and down arrows, the key travel is large enough for such a narrow up arrow, and down is also rounded, due to this, when switching from a much larger key down to epre. up key, you often also cling to shift
4. Waterfall keys or rounded bottom keys are a bad idea, especially on the arrows and spacebar, which are constantly accidentally pressed if you move the keyboard.
5. Due to the rounded keys, it is impossible to take the keyboard with your hand around it in the center, because you hold the space bar with your thumb
6. At first it seemed that the battery platform on the left is a very convenient solution for moving the keyboard, but, firstly, over time, the tray cover loses its grip on the compartment and as a result you get a quest to find batteries from a fallen keyboard, leaving only the cover in hands, and secondly, every time you try to take the keyboard with one hand from any of those three sides that you can’t take, because there the keys are right next to the edge of the case.
6. The grip on the mouse is quite comfortable, but after a year and a half the click wheel stopped working.
7. The Del, Home, End keys, you constantly have to look visually, since it is problematic to find them, and Fn + is also a gift for PrintScreen and Pause / Break.
8. When you are already tired of all the minuses from the previous paragraphs, you begin to notice that the mouse keys and the spacebar work very loudly.
