I really wanted these to work but I'm VERY DISAPPOINTED
I've watched the instructional videos multiple times, primed it (which was only supposed to have to be done once, but it's every time I try to use it), and used the crimping tubes provided. The crimping handles simply will not move unless the reset/tube holder handle is held down. If the handle is holding the crimp tube in place and steady, the other handles will not move at all. I tried and tried and finally just gave up. These are not worth what I paid for them, and they're more trouble than I need.
