After my 4th K800 keyboard died I bought an MX Keys S. I really am not happy with it. I have tried to get used to it and like it. It just sucks compared to the K800 that I loved and used for many years. The keys don't feel right. The Caps lock is way too easy to trigger. It sucks having 3 different usb receivers for different logi devices. Overall, I am no longer a happy customer. I'm a frustrated and unhappy one.
