While this is (barely) enough for my needs, the wires are very thin. At the very least, thicker insulation would help. They just feel very cheap. And there is no point in inserting anything else into the plug into an open socket. Is there a 3 amp fuse? And if you try to use that and the fuse blows, you're out of luck. There are no more radio shops, you are on your own. I use a piece of ABS plastic and glue to block this "handy" hole. But I would recommend this one just because I use it for my projects because I can't find another suitable one.
