I may be the resident expert. I have 4 of them. 2 small or junior boxes, a large or senior and a crossover.
The small boxes ride on tractors and combines. They have thousands of hours of offroad use. The large box rides on my truckqnd has had over150,000 miles on since i bought it and it was well used then. My crossover stays in the shop. The worst issue with any of them has been 1 broken peg and i welded it back on. They are nearly indestructible.
They are very weatherproof, store a lot in a small space, hold things in place very well and actually be tipped upside down with almost all items staying in place. Sight inventory is also very easy and they are easy to work out of. Most commonly used items are within easy reach.
My in shop storage is a mix of drawers and the crossover. It is much easier to find replace commonly usdd tools witbout having to open and close drawers or work from the top compartment of a chest.
