I too use a APC unit all the time at home. I don't experience brownouts that often here, but lightning and voltage spikes happen all the time. I've purchased 4 replacement APC units over the years at $100 each...........some of them had their insides totally melted!!.....................but have never lost any of my computer or music gear. As a utility mechanic we use these same APC units to protect the PLC controllers in many of the electrical panels where I work. They are very reliable and durable. -charley
