Just out of curiosity, how old is your surge protector? If you are buying refurbished versus new that may be one reason for the short life. Though most people either don't know or forget that when they buy a surge protector the the Joule rating is a lifetime rating not a per surge rating. In other words they should be replaced every 6 to 12 months and immediately after a surge. This time length of course varies depending on your particular areas power stability and storm tendency.
Just a thought, a lot of times when my members have come to me for a bad item it was usually plugged into a surge protector that was 2+ years old meaning it wasn't protected very well and likely not at all...another weak protection point has been when they don't surge protect their line in to their modem and then connect to the router..
Asus's RT-AC66U achieved superiority by defying FCC regulations
As it turns out, Netgear and Asus arrived at a settlement in August 2014, the terms of which were not disclosed. Today, Netgear brought to my attention the fact that Asus had also settled with the FCC in August, admitting that it violated the agency's regulations and paying a $240,000 civil fine.
