Input:
I purchased this surge protector in June 2017 to protect a TV and components.  We live in the country and the power sometimes goes off and on and there are surges that have damaged another TV.  Well - I was away and when I came back nothing on the protector worked (no power).  I pulled out the surge protector and it smelled of burned electronics and there was no power to the outlets.  I just opened it up and the insides were clearly burned with black soot inside.  I guess I was lucky that it didn't start a fire!  At last the TV was not damaged.  All other electronics that were not on the surge protector are undamaged so I don't think it was a "super-surge" or something that caused it to burn up.  I'm not sure if others have a similar experience but, needless to say, I am very surprised and would not recommend this unit for use to protect electronic equipment.
