Impeccable quality, very conductive
With these plugs the production quality is very good. The surface finish looks even better in reality than in the pictures. While the connector shells are all metal including the surface finish, so it is worth noticing that the only non-conducting part of the connector is the colour band. The connector shell is fully connected to the signal, so maybe not recommended to use these in applications with high voltages present while handling.
The spring structure of the golden part is rotating, which means the connector migh be less prone to breaking when twisted inside the mating connector. Robust double screws allow rather thick wires to be used and secure connections to be made. Overall rather decent quality/price ratio and very good build quality.
