Bests & Worsts Reviews from Amazon

First off. My battery backup flagged this product as "Building Wire Fault". The product showed 119volts at 58hz. My lights flickered like I was in the early 1900s. After checking all my indoor wiring and power strips, only this inverter remained. Dismantling this product, the side "Heat-sinks" proved to be plastic. Worthless props. I discovered the connections from the AC plugs had the "hot" connection soldered into the ACN (neutral) and the neutral wire soldered into the ACL (load). I soldered the wires into the proper positions, and after re-installing, still received the "Building Wire Fault". I took the product apart again, and after discussion with another electrical technician, we concluded this product had no ground included on the neutral side of the AC. I soldered a wire to the neutral side, and attached a ring terminal to the ground screw in the back of the device. Reassembled, and re-installed, flipped the switch, and have a functioning product. It now reads a steady 121 volts at 60.3hz steady. My lights don't flicker. My power supply shows a properly grounded device. I am writing this review on the power from the inverter. Bottom Line. VERY dangerous product. Not compliant for USA standards, and I don't feel the average person on the street wants to have this "Shock Hazard" in their home. Just Saying....
