The keyboard is good, if you do not look at the price tag, Will fit perfectly into the ecosystem of Logitech devices, But for its price segment, the keyboard is so-so, there is no point in taking it without other devices from Logitech. Pros: It is pleasant to type on the keyboard, how it sounds, its response. The cover under the keys is made of metal, which is good, the plastic can be rubbed off when cleaning. Bright and good lighting. Weighty and big enough. Cons below: Disgusting key cover that wears off after a month of active use. An incomprehensible open space under the gap, which acts as a dust collector, it is not clear why it is needed, this makes the keyboard much more vulnerable to water. The backlight can only be adjusted through software from Logitech, if you use other programs to change the color, it is constantly reset to the previous color, which is inconvenient if you do not have all the devices from this company. The application is disgusting, it constantly hangs, sometimes it needs to be reinstalled, as it goes into eternal launch, it is intuitively inconvenient and incomprehensible, it constantly changes color if there is an application with integration. Some keys become tight after a while for no apparent reason.
