Because the first one broke when I washed it to get rid of the dirt, I have already purchased a second one. When I work on a computer, I use a unique white keyboard that I purchased myself. It was convenient that the keystrokes were silent and wireless. I was very happy with how well the ergonomics worked out. Regarding the function keys, they are able to be configured, and once done so, they will function in the same manner as they do on standard keyboards. After working on it for a quarter of a month, this is only the initial impression I have of it. After only a few days, I was able to train my fingers to almost completely ignore the keys on the keyboard because I had become accustomed to the layout. The keyboard was convenient for me.
