How long you have been using the keyboard ? Mine got screwed after couple of months of usage (I took really good care of it as I had read about the initial backlash)
Reading about all the keyboard woes others had, I've been wondering if I am just lucky. In November 2018 I've traveled to another town with my laptop (in the sleeve, as usual). This was single day travel and it turned out that I've didn't even have to pull it from the bag a single time. After coming home 10 hours later I've pulled my laptop from the sleeve and pressed "R" key. It didn't "click". I've pressed it again. It didn't click either, but it sticked to the tip of my finger and popped out of its slot. I was now part of the people blessed with keyboard fault.
