This fuse holder works exactly as intended. I installed it in my Xterra's engine bay to hold the mega fuse for the inverter positive cable. The lid takes a minute to figure out how to remove without tearing the device, but it's easy enough to figure out that I know exactly where to put it back together. The only thing that really bothers me is how small the lug holes are on either side. I used 2/0 grommets and they were too wide. I had to cut the plastic to fit. It didn't matter much, but it was a little annoying.
