A suitcase takes more punishment in one flight than a year of use at home — conveyor belts, baggage handlers, and being stacked at the bottom of a hold.

Covers take the scuffing that otherwise lands on the shell, and make an identical black case obvious on the carousel. Straps hold a lid shut if the zip gives out under pressure, which is the most common failure on an overpacked bag. Wheel guards protect the part that's hardest to replace.

If you also want tracking and locks, the luggage security range covers those.
