Over the past 20 years I have owned various laptops from HP, MSi, Acer, Apple, and also (for my desktops) external keyboards from a number of additional vendors. The only keyboard that ever had any trouble was after I gave it to my 4yo and over time he got all sorts of food inside it.

My work 2018 mpb showed a stuck key after 2 weeks (no food near it), and it obviously is not bad luck on my part.
