Bests & Worsts Reviews from Amazon

After reading stories about RV owners experiencing a surge, low voltage or bad ground which seems to be the biggest problems; then the financial cost of the repairs, I bought one. With all the electronics in the RV plus the additional items like plugging in a lap top, cell phone, eBook reader, ice maker, etc...A low voltage, bad ground or surge could cost hundreds or thousands to replace or repair all the appliances and wiring; plus the protection of a possible "open ground" or "ground fault" that could lead to electrical shock and result in personal injury. There are 2 major brands: Technology Research Corporation (TRC) Surge Guard and Progressive Industries. I had a TRC brand product for a couple of years and then I purchased a Progressive Industries product. The reason I bought a Progressive Industries product are as follows: 1. Made in U.S.A. (TRC not made in America) 2. Lifetime Warranty (TRC 1 year warranty) 3. Surge Indicator: If surge protection failure occurs within the system, the Progressive product has a "Surge Indicator" that alerts you of the system failure. (TRC does not have this; the TRC product will continue to operate but provide no protection) 4. Open Ground Protection: If the pedestal is not ground properly your RV will still operate but you and your RV become the ground; this is not safe 5. High/Low Voltage Protection 6. Time Delay for A/C Compressor 7. 3-Mode Surge Protection 8. Reverse Polarity Protection 9. Open Neutral Protection 10. AC Frequency Protection 11. Accidental 240V Protection 12. Built-in Lock Bracket: Allows the unit to be secured to the power source to prevent theft 13. Made in the U.S.A. and Lifetime Warranty
