I used one form or another of this device for 40 years when I was a union electrician. like most others. A wiggy will never replace a good VOM except in one area. Security. It is not fooled by "ghost" voltages, induced voltages that aren't there, or RF interference. It doesn't matter if you have AC or DC power, it actually identifies it for you and you never have to remember if the wires are connected to the correct terminal. When the magnet moves the piston, you know there is voltage there. You can feel the action of the electromagnet in your hand and see the voltage range on the scale. This model is an evolution of generations of voltage testers and works well. No real electrician can do without it. Interchangeable wires in this model are a plus.
