peace of mind
Review by
This adapter gives me peace of mind when plugged into shore power. Lightening strikes don't worry me anymore. The read out is perfect. The value is a lot better than what it would cost to rewire
Progressive Industries 50A EMS
Review by
Replacing another brand that failed after 5 years but only had a 1 year warranty. The lifetime warranty on the Progressive Industries EMS is a definite deal maker. The physical appearance and construction materials are both impressive. Service from Dyers was great as always and they had the best price in the country.
Great product
