there was some interest in them but the people who looked at them had upside down plugs -- electricians in this area of TN don't realize the polarized plugs need to go a specific way so things can get plugged in correctly (have the same problem in my addition) so everything has to be plugged in upside down... (the larger slot on the outlet is on the right instead of the left and the little hole is on top)
Here in Arizona, the building code states that all electrical outlets will be installed with the grounding hole towards the floor (right side up) WITH THE EXCEPTION OF THOSE PLUGS ATTACHED TO A SWITCH ON THE WALL - then the grounding hole MUST be pointed towards the ceiling (in other words upside down) so that the owner will know which wall outlet is attached to the switch by the door.....oh by the way - only one of the two plug outlets is attached to the switch - - - GRRRRRRRRRRRRRRRR
