Surge protector is a lie?

I have a Micromark surge protector. Just a plug (not as in to connect an appliance, it just plugs into a socket to absorb surges, no cable comes out of it). I was interested in the LED on the front which says "protection active", so I opened it to look inside to see how it knew if it had expired. What do I find? An array of varistors as expected, but the only connection to live was through a clumsily soldered on piece of fusewire about 1-2 amps thickness. So.... it blows the fusewire as soon as there's an infinitely tiny surge, so therefore can't absorb much of it anyway? What's the point in that?

You're lucky that didn't cause a short with the stupidly unfused incoming setting fire to the wood.
