The converter itself works fine but they don't include, or even have in stock the other half of the 12 volt output plug. Since I couldn't find anybody that had anything even close to fitting it and I had to connect it to an existing fuse block, I needed to cut the 12 volt plug off and crimp on some regular terminal ends to make it work. If you are going to sell a piece of electronic gear that has a proprietary type of plug, you should include both halves of the plug.
