...The Power Ports also have an isolated ground. This means that the ground connections of your AC plugs are not common to the strap that affixes the outlet to the wall housing. In many homes the boxes that contain the receptacles are grounded through the house wiring or the metal pipes that contain the wiring, and leaves you little to no control over grounding... They are incredibly easy to install... remove the cover plate. Remove the two screws affixing the existing receptacle and pull the receptacle out from the box. Using a Phillips screwdriver, simply disconnect the wires from the existing plug and place them on the Power Port.

So in most cases the receptacle will be ungrounded.

You can even run a 15 amp circuit on the bottom plug and a 20 amp on the top plug or vice versa.

This is a 20 amp receptacle.

This isn't just misleading it's wrong! Can't something be done about these guys?
