"I received an emergency call when this happened because he was camping with his family and was unable to use anything powered by electricity"
Although I didn't get a picture of his burned plug at the time, below is a collection of similarly burned plugs. You can see that there can be enough heat to char, melt, or even set fire to the plug.
"It can only go in ONE way, and the SmartPlug has a very satisfying "click" when the side tabs connect."
It gave me peace of mind that my family would be safer from a potential electrical fire. I never question if it is connected correctly because there is an LED light on the outside to let me know all is good. The cover of the outlet also folds down to create another "click" and an additional security feature for stability of the connection.
"I recommend that all RV owners add a SmartPlug to their list of after-market upgrades."
