My B, and Up/Down Arrow keys were either hard to press or would “double” events. I now have a compressed air bottle next to my desk. It seems to do its job but I never had to do this with my previous MacBooks! Another issue I face is pain in my first finger joints (right below the fingernail bed) after a long day of typing. Maybe I just have heavy fingers but the old softer keys were less harsh. Another unrelated (we’ll it is like a keyboard, right? :) issue is the TouchBar requiring two taps for most things. I even have my TouchBar as “static” with just a few buttons.
