Review on ZYAMY 50Pcs Scotch Lock Quick Splice Wire Terminals Cold Pressed Insulated Snap Lock Electric Wire Crimp Connectors Cable Joiner Yellow For AWG 10-12 by David Norwood

I bought these for connecting 12 gauge wires. They are designed for 10 and 12 gauges. Tried different connection methods with different pincer configurations. Only 1 out of 5 worked. And I think it was an accident. I went back to the tried and tested method of wiring wire nuts or plugging straight into an outlet etc. It works every time. Don't waste your money on these connectors.
