Review on Antrader European Connector: Enhanced Aluminium Reinforcing Solution by Michael Tegan

I only need Winkel 3030. The black ones were cheaper so I ordered them. I should have just used the bare aluminum ones. The paint used on the corner brackets has already peeled off in the packaging. Because of these things, my entire workspace is covered in black dust and paint shavings. They're pretty gross, but they work great up to 3030. But they look terrible.
