Re: Progressive Industries EMS new owner problematic lifetime warranty support Reply #25 – January 29, 2018, 10:10:25 pm Hugh Autoformer has its place, but is not a suitable replacement for EMS. Beware of any device that uses the term "Surge Protector" as this term does not indicate that the device will DISCONNECT when voltage is too low or too high. Surge is a way over-used word and is often over-promoted to sell devices. With the inconsistent campground electric service often found, over / under voltage protection is needed. 'Over' will include protection from 240-volts where 120-volts is expected, something that would have caused thousands of dollars of damage in a split second. Surge will NOT protect from this.
