Review on Optimized Automotive Standard Profile Shaped Pickup by Leo Fairchild

I couldn't figure out why my trailer wasn't getting power from my truck. I found that my fuse has blown. It worked fine. Put in a new fuse and you're done. IT WORKS OUT! I don't have the slightest idea of the quality or durability of these, but given that my truck is 10 years old and these types of fuses have been around for at least that long, I don't think there's much more to say. It worked right away, there's no reason to think they won't keep working unless I overload the circuit.
