Crutchfield Customer Review (What's this?)
The kit does have a lot of the odds and ends, including things that, if you're a first time installer (like me) you might discover useful. That said, the crimp tool itself is junk. It doesn't open well, the grips slide off easily, and it's painful to use well. The wire cutters were poorly machined and didn't do much of anything. I'm going to suggest that, if you're buying this and have other experience with a similar tool, you're going to be angry at yourself for a while, then you'll figure out how to manage it and move on with your life.
Pros: You can add it to your existing order so you don't have to go elsewhere for a tool. Kit does have a good assortment of things.
Cons: Everything about the tool. You may not need or even know how to use the other things that come in this pack.
