Pros and cons

Pros

The claimed 21-cubic-foot capacity provides additional roof-level luggage space for road trips.
A soft-shell design and compact-storage description may appeal to buyers who need to put the carrier away between trips.
The listing claims compatibility with both rack-equipped and bare-roof vehicles, offering more installation options.

Cons

A soft carrier requires securing and loading luggage rather than providing a rigid cargo platform.
