I bought this product a year ago and I thought it was great to keep my internet router and WiFi router plugged at a wall location behind/ adjacent to a sofa. Recently, I had massive issues over a 2 month period with my internet. Having had many technicians come to out replaced 4 routers no issues were being resolved until the last technician came with a voltmeter!! What happens next shocked me. He finds out that this surge protector was not regulating electricity even as the green light is on and shows protected. Upon putting a voltmeter it showed really high output which is the reason the internet router adapters kept blowing out several times causing, internet outage. This is supposed to protect and regulate electricity and it did just the opposite. Look at other brands if you need true electricity regulation.
