The crimper takes some patience to make sure you are getting the technique right. Key thing is not to remove the pins from the strip until after the first crimp which means you have to bend the pins you aren't using out of the way. You also need a good wire stripper that gives a nice clean cut on the insulation without nicking the fine copper wires.
