The product is high quality and very well designed. The installation video was helpful. The stainless steel construction insures the box will last for decades which is important for a 4Runner that can also last for decades. As mentioned by other reviewers, construction, materials, fit and finish were perfect.
Having the included hardware was very helpful. I found having the nylon locking nuts on the outside of the box better for easing the
placing a battery in the box.
