Tool worked well reasonably priced, no instructions came with the tool, study how to use it prior to wasting a coax pin.. coax pins are not sold separately. If you ruin the pin you will have to buy a new connector assembly.

Good, solid tool but no instructions included, made in Taiwan.

First crimp with a new out of the box crimper. Installing the center pin the crimp failed, center pin pulled off. This not where I wanted to be with a new tool. Frustrating.
