Crutchfield Customer Review (What's this?)
These crimp caps are great, they are soft and malleable, not brittle like cheaper ones. They crimp easily without shearing, and hold the wires better than other cheaper crimps. Use with a good set of crimpers for best results.
Pros: strong, flexible, high quality, easy to use.
Cons: Might take up more space than a straight crimp or a soldered connection.
