Review on Experience Ultimate Protection with ⚡️ the PROGRESSIVE INDUSTRIES EMSHW30C Surge Protector by Jerome Godwin

I fitted this to my new trailer myself. I've researched many of them over the years and finally decided that when I buy my new pendant I'm actually going to put them on. I like that it's permanent and installed in the trailer where I can't be stolen. I love that it has an on/off switch just in case you have the nerve to bypass any warnings. If you sometimes over or under voltage and it's a bit higher, you can just go ahead and use them. While not recommended, it's nice to have the option. I am very happy to know my trailer is protected and I always know if there is a problem with the wiring I am connecting to. I connected to a friend's garage and the garage had reverse polarity wiring. The device would not turn on and gave an error. I would definitely buy this device again if I ever had another trailer.
