Review: Valuable Device For RV - Rugged build and works well. Indicator lights are easy to see, even from inside the RV and allow you to monitor electric circuit status. Would definitely buy again.
Review: Works Well! - I like it so far, had it for a 1.5 months. I am concerned when it starts raining, thinking I will build something to cover it up during the rainy season to protect it from the rain. Some reviews comment about this device getting water logged and failing. It is now the rainy season, I have had this surge guard for 9 months. I covered the surge guard and cable power plug connection with a heavy plastic bag. I see the bag has deteriorated and exposed the connection to the rain. This protector has blocked a surge for me on 2-3 occasions now and reset itself, it has worked perfectly. I found another cover for it and am trying that to see if this one will work better. This surge protector has now pasted the hurricane test. When power came back on last night it worked perfectly. I had no problems and everything is working as it should! I would recommend this surge protector.

### ⭐⭐⭐⭐⭐ This Surge (50 amp) is a great product and has proven itself
*by D***L on March 2, 2018*

OK, I see a lot of negative and positive reviews of this item. We have had 2 since 2015 and camp just about every weekend, so it is always in use through all kinds of weather conditions. Rain, Snow, Ice, Sleet, hot sun, -5 degrees, all conditions. We have a 38' TT and it saved our electrical system on several occasions. Once the Surge took a big hit from a Thunder storm, it saved our electrical system but since this item cannot be reset, we had to replace it, which I had no problem doing since it did its job. There are other times we found the CG Electrical post was mis-wired, thanks to the Surge Light synchronization. This Surge (50 amp) is a great product and has proven itself, at least in my world as noted in above FACTS. Very happy with this Surge. (tip: always plug the surge into the source, insure you have all 5 green lights before hooking into your RV)
