Construction is solid and what you'd expect. Removable dividers are handy. I'm not impressed with how it mounts - in fact it doesn't mount to the vehicle at all. It comes with brackets to mount to the seat bolts and then you strap the unit to the brackets with nylon straps provided. So it floats around under the seat connected only by the straps. It's shaped to fit snugly under the seat and admittedly doesn't move too much. It's been installed a couple months now with several trips back country and it's worked well. It's big enough to store a Viair air compressor in one compartment, so it adds a decent amount of organization capacity. I'm not impressed with the installation but it does work.
