Review on Ratcheting Wire Crimper With Heat Shrink Connectors - TICONN Crimping Pliers For Professional Results - Ratchet Terminal Tool - Reliable Wire Crimping Tool (30J, Blue) by Derek Faseworld

When I received the crimper I thought it was defective because every time I tried to crimp a quick disconnect connector, the wire would easily slide out. After a quick google search I realized that the tool just needed to be tightened a bit in order to work. There is a little gear near the base of the grips with a + and - on it, if you remove the screw and carefully push the gear towards the +, the crimper will tighten and make a much more secure crimp. After tightening, it seems to be a very good crimper.
