Review: Fuse in package is different from the fuse in the listing photo but it is a legitimate product. I contacted Blue Sea and they confirmed they have changed suppliers and are in the process of updating marketing materials.
Review: This company make very good fuses. I use the mega fuse in a inverter build I have an works great. Stay away from those ANL Cheap crap. Well unless you want your house to burn down. These are the best way to go, just get a quality fuse holder to go with. Some note.... YES THEY ARE HARD TO SNAP IN HOLDER.. They are supposed to be that way. You push fuse in holder first then mount the holder. Easier that way. Quality an great company don't miss out
