Seems fairly typical for around here. Garage door openers are one of those things any idiot can buy and install, and consequently, you have every idiot buying and installing them. I had a neighbour who ran his on an extension cord that ran out the bottom of the garage door itself and plugged into a kitchen outlet at the back of the house through a slightly cracked window. The best part? When he installed the opener he drilled through the CLOSED garage door at the bottom to run the cord! Wish I was there the first time he used it...
