Impressive accuracy
This was the first accessory I bought after buying my fifth wheel RV. I have a pad to park my RV on while at home complete with a 50 amp receptacle. I keep it plugged in during non use times because of the residential fridge and to keep the batteries charged. I have a surge monitoring system in my home and my voltage is extremely stable. Because of the distance, mine is the only house on the transformer. I got a notification on May 8 that my voltage had surged to 132.8 volts and apparently remained there for 12 minutes. I hadn't been in the RV for several days until yesterday. I noticed the clock on the microwave was flashing like there had been a power outage. The Surge Guard had apparently sensed the surge and opened the circuit. The 132.8 volts (if accurate) is only 0.8 volts above the +10% tolerance level; that's extremely accurate! I have always had a high degree of confidence in the Surge Guard; now my confidence level has risen to extreme level of confidence!

not rainproof
water has gotten inside this surge protecter and the middle light has completely stopped working because of it. The other two lights will do the same before long, because I can see there is water there as well.
