Viborg quality control should be better
The VF518 should have a metal body, like in the picture shown. It looks like Viborg puts VF508 plugs in a box that says VF518. Hence the Audiophonics description that says it has a nylon body. But I believe that is due to Viborg putting the wrong plugs in the boxes.
The plastic body is nice though, so I will keep it.
Don’t expect Furutech-type bolts, the Viborgs bolts/ screws are smaller and weaker. But Viborg plugs are also cheaper.
Only 2 stars because of the bad quality control of Viborg, although I am still satisfied with the plug.
