Great for non-professionals.
Crutchfield Customer Review (What's this?)
As someone who does not have access to all the great tools in a fully stocked car audio shop this product is great. It's very hard to justify getting an expensive crimping tool when, at most, I need to do less than a hand full of large cable crimps every few years. With a small bag a ferrules and these terminals, you can get strong crimp like connections without all the large expensive equipment.
Pros: Compact Easy to use Strong Professional quality installation.
