Can you answer the questions and write comments about my surge protector ?
I have a cheap surge protector. Can you write a comment about it whether it is nice one or CRAPPY one ?
Can the LED of it, show the MOV status whether it is working or malfunctioned ?

I have another one in my living room. (The same one.) The LED doesn't glow. So, did the MOV actually malfunction ?

The manual says: "You must use surge protector with a wall socket which has ground wire." My wall socket doesn't have ground wire. But the MOV also doesn't have a contact with grounding. Does it matter having grounding or not in this situation ?

Yesterday, I had a problem with electricity. HDD rpm a bit lowered and after that, it returned the actual 7200 RPM. Also my PC restarted itself. When I looked to the street, I saw the all street lights are turned off. (Probably voltage fluctuation or something.) But PC works now without a problem. So, did my surge protector covered the PC or not ? (PSU: Seasonic S12ii 620W)

Here are the images about my surge protector:

Seems like nobody interested in surge protectors. :)

Honestly I didn't even see this thread until you bumped it. :D

Too busy right now to pick it apart, though. Maybe later.

Hey, I think I can help you. Will take a look at it right before Christmas, so stay tuned :)

This is what a good surge protector looks like inside (Tripp Lite isobar ultra); much more than just MOVs. A clever surge protector doesn't just absorb the pulse, but also reflects it back out.

Why has the LED got two resistors on it? And the rails should be 0V (neutral) and 230V (live)
