What I found the most impressive is the fact that this Rean connector has the same cable gripping system as other Neutrik plugs. With it, there is no way that a solder point can get loose due to a cable moving around. That was the reason I bought these connectors.
Another plus is that the connector is gold plated which makes it corrosion resistant.
The only downside of it is that it is quite long and chunky, so if you don't have too much space around the female part of the connection, you should maybe search for other solutions.
