AudioMagic Fuses Bad Quality I Do Not Recommend!!

If "stuff gushing out" I'd not be using the fuse, sounds like a hazard waiting to happen. Call the company and show pics and inform them if a fire happens you will file a law suit, that should make them replace the fuse for you.

How much 'gush' can be in a tiny fuse?

The nano-liquid can get everywhere because, well, it's nano.

So, the liquid's coefficient of expansion exceeds that of the glass and metal, forcing the fluid out when the thing heats up? Great engineering.

Who in the blazes thinks it's a good idea to insert something full of liquid inside a piece of electronic gear??!
