In addition, after 5 years, the paint of symbols on several keys began to be partially erased, the top row of function buttons was not very convenient. I don't consider this a disadvantage. Has pros: 1. Quiet. 2. Soft pleasant key travel. 3. Decent appearance. 4. The keyboard is universal, it can be used for both typing and gaming. Has some cons: 1. In the sixth year of use, the keys began to get stuck, it is now almost impossible to use the keyboard. In order for the keys to be pressed normally, you need to hit exactly in the center of the key with a strictly vertical movement. And so on all the buttons, the factory lubrication of the mechanisms apparently dried up. 2. The keyboard is not comfortable enough for touch typing. For 5 years, I have not gotten used to it until the end.
