Last July 15, at the FMCA Convention in St. Paul, I purchased a Progressive Industries EMS-PT50C surge protector with voltage protection. I had had one installed (hard wired) in my '03 Beaver and it always worked great. Never a problem.
This portable version lasted 10 days. On July 25 it started displaying 250 volts on one leg, which was incorrect. I contacted the manufacturer and they replaced it.
In September, my replacement PT50 started shutting off, indicating a ground interruption. It continued to do this at every connection, which was in error.
The "replacement" PT50 was returned in November and a replacement was received. This one worked fine until I unplugged it to go to Titusville last week. Plugged it in at TGO and the LED display is blank.
This makes 3 failed surge protectors in less than 6 months.
I contacted the manufacturer and asked for a refund this time, instead of yet another replacement. But, no dice. They are only offering a replacement.
If you are considering this product, I would steer clear. Apparently, they are not living up to their former level of quality control and performance.
Looks like $400 down the drain !!!!
