The power companies have these to cut down on the # of meter readers they have to pay, if your paying your bill and keeping a tight hand on security you shouldn't have any issues. I've been a licensed electrician for over 15 years and there is no way they can tell what kind of appliance is drawing what kind of energy, that is some funny shit! Amazing how much bullshit get spread on message boards.
Good luck, Peace
