I was just ordering some wire from Stealthvape, and noticed that they are now the Lost Vape service centre and are selling replacement button assembles and long screws for the Furyan.
Thanks for that @Huggett. I recently bought a second hand black/silver Furyan before finding out about issue with brass screw/rods going into stainless steel top plate, and one of my rods is quite loose, so I was very happy to find a trusted source for replacements.
