I wanted a small light pack that could be transported inside a larger suitcase; the inflatable structure of this case looked promising. The pack was intended to carry a DSLR with attached lens, maybe a 2nd lens, plus small items and maybe a water bottle and could be worn while hiking/climbing over steep/broken rock. Usage would be intermittent and temporary; a heavylduty case would not be needed. The illustrations for this case seemed to show a hose-type air connection that would be amenable to inflation by mouth; this is not the case. A pump would apparently be needed, though some other options will be tried. The catalog illustrations failed to show the interior partition assembly, which might have provided some warning. However, after over an hour's study, I was unable to assemble the partitions in a way that would provide positive support for a DSLR-lens combo; only rectangular compartments are apparently possible. With the amount of materials used, an excellent partition design could have been accomplished--didn't happen. Not hard to see why this unit was sold off at half price. Very sad considering the generally good quality of materials used. Returning to Adorama would likely cost more than the unit is worth.
