Low quality. Recommend something from a better brand.
Low quality. Seemed fine until the first one I ordered one of the terminals broke off with very little tightening force. The replacement i had ordered worked for a few days then quit working altogether. Overall disappointed.

Functional. Be careful when tightening nuts...strips very easy
Quality is questionable. The poles will strip way to easy. So be careful when fighting down. I had to use a stack of washers on top of wire to keep the nut tight. As far as functionality goes ..been doing great for over a month.
