Product was as described. No instructions for install but easy to figure out. I put the closed end of the box up under the dash first and then worked it back into position. Mark and pre-drill a few of the holes and it'll be easier to secure in place. They answered my questions via chat very quickly and were good to work with. Will be buying from them again.
