The guys over at GizmoSlip, who test the durability of consumer electronics by dropping them from various heights, got their hands on the Nintendo Switch and tested it.
After five drops on concrete from 5 feet, the Switch worked just fine, but the exterior showed a lot of scuffles and scratches, as expected. But after about 5-6 drops, the Joy-Con controllers see to take too much damage to function properly, but the console itself runs just fine.
In fact, the console worked fine even after 10 drops.
One interesting thing that the video shows is the Switch is very wobbly when it hits the ground, as seen in slow-motion on the video.
