Review on Power Up Your Devices Safely with Topzone's 6-Outlet Wall Mount Surge Protector: Featuring Dual USB Charging Ports by Andy Thorson

Green light indicates proper grounding and red light indicates surge protection is working? There are no instructions in the box or on the blister pack or on their website. So I'm assuming my ground is fine because I have a green light on and the surge protector isn't working because I have a red light on. I'll keep it anyway as I bought it for six 110 jacks and two USB slots. It would not cost them anything to explain the bulbs on the blister card. However, that would be half because red means bad and green means good.
