I use 3 of these half crates for organizing my inventory of IT supplies and spares in the back of my car as a travelling IT technician. Total gamechanger from the loose cardboard boxes and flimsy bins sliding around the trunk. They're pricey, and definitely don't cost nearly what they're charging to manufacture, but there's nothing else on the market that is as efficient in its use of space, and as versatile in its dividers and modular lids. The tool stacks flooding the market such as Packout, Toughsystem, Pro Gear, etc. are often too burly and have an incredible amount of wasted space taken up by that burliness and extra hardware. SIDIO strikes the balance between durability, lightweight, and space efficiency. Sure, it's probably not going to survive being dropped from the bed of a truck unscathed, but I don't need it to. I keep finding new applications for SIDIO crates all the time, and after biting the bullet on price, I'm always very satisfied with how much I can stuff in these things.
