The plastic housing of the Quest controllers are really thin in order to let IR light through so it can be detected by the headset. This results in fast damage or little bumps if you accidentally hit a table, wall, cat, husband or wife. If Oculus designed a transparent (sillecone) protective cover we can buy one and put it over our controllers so it can absorb the damage and avoid scratches when we hit a surface without blocking the IR light. This results in longer lasting controllers.
