They are good and serve their purpose, but it is not always easy to mess them up properly so that a cable can slip out again and then you can throw the connector away

Good item they works very good with wires. It's value for the money.

Everything OK. Fast shipping, not tested yet.

Very good and fast for a long-lasting connection
