Everything is fine on the first day, the charger is amazing. However, I got hit in the face when screwing in the screws during installation. It then appears that the wire screws on the side made contact with my metal socket. So when I installed the other one, I had to run tape all over the socket to insulate the points of contact with the box. I hope they make the device smaller or add a protective case to avoid this. I was lucky that I was wearing safety goggles and gloves when this happened.
