I had thought that there would be an upgraded version of the K310 in terms of its usability - see photo - however, to put it gently (especially when you compare pricing), it turned out to be not very good. I now understand the primary reason why the mx master 3 and the mx keys are incompatible: although the mouse is designed to be used with the right hand, the proportions of the mouse do not let it to be put on the right in a comfortable manner since the keyboard contains a numeric keypad. Purchased in conjunction with MX Master 3 for use in remote work due to the fact that the Poppy Keyboard is missing certain writing buttons when used both under Venda and in the Shell. helpful information (a forced change to the layout): iOS: Fn + i macOS: Fn + o Windows: Fn+p Logitech Options does not take precedence over the settings for the keyboard, but it does take precedence over the settings for the touchpad; where is the logic in that, Logitech? I received the idea that the product itself is not terrible, but that the software makes everything terrible. I emailed customer service, and I received a response 9 days later. The solution is that you need to go to the product registration guide, register your device, and then request that it be repaired. The company will get back to you in three days.
