Like others state, the connections are amazing. It was easy to install. However, the reset was difficult. I even pushed on to with a screwdriver, but it would not "pop". I alternated between both and flipped the breaker, over and over. I was about to call an electrician but tried one last time after walking away for an hour. It "clicked" after the third hard push. Now it works as it should (I tested it a few times). I would not purchase it again though.
