In general, it’s worth buying if it’s a tool for work, I wouldn’t take it for games. Its pros: Very pleasant tactile sensations. For those who work a lot at the keyboard, that's it. Heavy, on the table lies like a glove. The left shift is larger than that of the previous K800 top keyboard, which is good news. Holds a charge for a long time, charges from Type-C. Different cons: Of the shortcomings: instead of PrintScreen, ScrollLock, Pause / Break, buttons for switching between devices were stuck, well, this is a completely unused function, and standard buttons are still used more often. Does not like dirt - the keys immediately respond. K800 was less capricious in this respect. Price! More expensive than a good 1Tb SSD.
