This stow box is well designed and the overall quality is good. The material used for the box construction is a hard type plastic that feels thin and my only hesitation with it is in cold temperatures I would be concerned it could be susceptible to cracking with an impact from loading other objects into the truck bed or something that isn't secured sliding into the box. The hardware included seems durable quality and heavier duty. The locking mechanism on the box lid seems to be solid enough and I like that the box also came with a paddle lock to secure the hinge bracketry as well.
