They are great for some things and poor for others.
If you want to transport a swarm pick-up, they are great. They are light, easy to close up, no bottom to slip off of, and the frames do not swing in the box.
For temporary housing they are ok.
If you want durrability in the yard, you are wasting your money. Even being wax coated they do not stand up to rain very well, covering will extend the life of the NUC(leus) box.
