The magic lies in the dies, they're made to be used with a specific connector. The HF one might not be an exact millimeter by millimeter copy of the "legit" ones, but in my experience, it does the job for the backyard mechanic, where most of the time we're probably using some hardware store brand connectors anyway. For $10, give it a whirl and see if the connectors stay on when you pull them. If they do, your golden.
