So when you drop on your head from height of 1 meter, no healing is needed? I'd guess so based on your comment.
I'm not sure about Mikrotik hardware, but many HW come with "shock rating" ... operating and non-operating, usually rating is around 1g ... so if such device fell from height of 1m, it should decelerate 1m as well (free-fall is 1g). When your device dropped on the floor, it experienced deceleration anything between 10g and 200g, depending how exactly it fell on the floor (if it fell on a corner, allowing it to roll before stopping, deceleration was nearer 10g but adding angular acceleration/deceleration which stresses materials as well, if it fell flat on a side it was probably 200g or even more).
Devices, meant to experience considerable forces, are engineered and produced differently. And definitely cost more. One example is automotive electronics, it's made much sturdier mechanically (constant vibrations and mechanical shocks), electrically (wildly varying voltage and noisy power supply) and environmentally (moisture, liquid water, dust, extreme temperatures)
