Input:
Great surge protector for the entertainment center. I like that it protects coaxial cable lines and Cat5e Ethernet lines. Very durable product and Trip Lite provides great customer service. I have emailed them and called them a few times with questions and they have been very responsive. I own three of these and a few other Tripp Lite. Great company with a great product.
