Recently, uncle bought one cheap surge protector powerstrip from MR DIY store at RM24 something?

But, to uncle dismay, the MOV is installed at wrong place. As the result, only one socket is protected from possible surge while the other three are not.

Some pictures below (large image):



Searching around the net for the MOV model returned:

Data from https://www.sunrom.com/get/559199 seem to indicate:

Aside from the wrong MOV placement in the powerstrip, the MOV itself is fine for its intended purpose.
How in the world this thing qualify as surge protector when it only protect one socket out of four sockets?
