These are absolutely fantastic inline fuses for your amplifier or battery hookup. I got the two pack of 200 because I am running a 4,000 watt amp that requires two separate positives as well as two separate negatives. They are the perfect size and easy to change the fuse. The top comes off easily. It comes with the tools you need to put the wires in or take them off. All in all, I feel like I got a fantastic value with these and I would definitely buy these again.

Perfect product for what I needed

This was exactly what I needed as I was doing an upgrade from four gauge to 0/1 gauge wire and adding a second battery so I needed two fuses and this worked perfect
