Wonderfully designed case with wheels to make moving it a one man job. The case is fairly heavy (see description for exact weight) and can be a hassle to move up stairs or across terrain where wheels cannot be used. This makes moving it a two man job, especially if it has equipment weighing more than 10 or 20 lbs inside. It is too bulky to carry single-handed and anyone who does it may run the risk of injury. There is a reason they show forklifts moving it in the promotional videos. I do not recommend taking this as luggage on a flight - consider a lighter, smaller (possibly carry-on) model unless you are hauling large equipment that ABSOLUTELY requires this level of protection. These things are designed to be on pallets in C-130's, not necessarily to be hauled around commercial airports. This thing has kept moisture out of it in the toughest of humid conditions in various portions of the North and Middle Georgia terrain. Not once have I had any issues with humidity when changing environments. With that said, however, I do recommend the desiccation kit if you are using it in very humid conditions, as condensation may be an issue. I personally haven't had this problem storing it outdoors for long periods, but I have not had to open the case in outdoor humidity over maybe 50% due to the limited times I check it throughout the year. So I defer to others on this issue. The case is sturdy enough for me to stand on it without it giving way in the slightest. The promotional videos show a truck running over it and, after my experience with dropping it, standing on it, etc, I can believe the fact that it may be able to withstand that. This thing will probably outlast me by a few millenia. Haha. Overall, it's a dang fine case that truly is military grade. I use this to store my most valuable items that are sensitive to the environment and I am seriously contemplating buying a few more for the other valuables that I need to put in long term storage. With these cases, you can literally bury them in a desert and not have issues.
