It was impossible to use it because of the lags. when the keyboard moved, a lag immediately appeared, then just in a stationary state. After deleting a large number of characters, the keyboard could simply freeze for 3-4 seconds. I changed it to mk 240, and I write from it, it works great, without the slightest delay. Different pros: Very comfortable, the keys are quiet and the stroke is small. The mouse worked without lags. Its cons: The keyboard lags a lot. The mouse is not pleasant to the touch.
