Review on ⚡ RockDIG Electrical Connectors Assortment for Terminals by Brett Slater

They all look beautiful, afaik, they are all made of shiny copper with no sharp edges, burrs or defects. They crimp well. The color coded shrink sleeves are good, compress well, feel thick and shrink evenly. I think there's glue, or maybe there isn't, but the filling looks amazing and won't go anywhere. I probably don't have to, but I do double shrink wrap sometimes. Satisfied.
