Review on 🔧 TICONN Heat Shrink Connectors Crimping Tool: Ratcheting Wire Crimper Pliers - Ratchet Terminal Crimper - Wire Crimp Tool (30C, Blue) by Patrick Gibb

No instructions other than those in the advert above. This tool is not easy to set up. You loosen the screw near the sprocket adjustment wheel and have to open and close the crimping tool to adjust. But how far you can adapt is anyone's guess. One setting literally crushes the terminal. One shot leaves a small gap and another shot leaves a larger gap. In general, it's not easy to see or tell which setting is too big or too small, other than tugging on the wire after crimping. If the wire comes out, it wasn't enough and you just wasted a terminal.
