I looked inside a 50 dollar Belkin ulta-supe-dooper-whammy slammy-ultimate surge protector and almost died laughing. (3) 10mm MOVS.
I now build my own. I call it a SPIKE CLAMPER. 20mm MOVS L to N and L to E. (3)each

MOVs by themselves react too slow. By trebling and selecting "largest in class" components, I gain vastly increased lifespan of the device.
