Very well made, heavily constructed. If you have one of the DuroMax generators, and an RV, nothing else will do. Do be sure to wrap it in a waterproof jacket. Face it, it's on the ground and moist is the enemy. If you're singing "Rain rain go away," and it's not protected, it's already too late. On the other hand, both the DuroMax and this adapter are top quality and means you can camp out in neverland.
