I have a personal 2013 MacBook that has been left running in a box in the desert for a week straight and filled with dust, had sesame oil poured into the fans, dropped, hit, scratched and heavily dented, but still works beautifully. Then the butterfly keyboard ones were issued at work and it immediately become unusable because of dust, randomly double hitting e or the spacebar or failing to register hits to some keys. YMMV, 1 apple computer sadly != another apple computer anymore
