I'm not a fast typer, but I do hit 80WPM pretty easily. This was done just moments ago on the butterfly keys themselves. So yeah, I'm probably hitting the keys a bit more than some other folks. May explain why the keys fail a bit earlier for me. For the record, I own a 2018 MacBook Pro 13" now. I've had every butterfly key iteration from 2015 (12" MacBook of every iteration + 2017 and 2018 MacBook Pro 15" from work), and every single one of them needed at least one replacement. Skipping 2019 MacBooks until Apple reintroduces scissor switches.
