So I guess I have never really put this thing through the test but I do live in an area where there are power outages. NO damage to any of my components (Sony 27" CRT TV; Onkyo home theater in a box system; Sony DVD player; Comcast Motorola Cable box). Not sure if it was the monster hat protected it or not but no problems. Color code is convenient and plug is flat to hug the wall. Good price.
