Review on Uxcell Inches Female Extension Connectors by Jermaine Shuster

Very good quality. I bought these extensions because of the built in locking clip which is a great feature. Unfortunately, I found that at least one of these cables has a steel core. The description that copper core wires are used is incorrect. In any case, I was disappointed to see that not all copper core wires are as advertised. Otherwise I would rate it 5 stars.
