The standard sensor comes on a J-card with battery. Pleasant LED COLORS, the additional bright LED spotlight is a nice touch. He seems to sense metal 80% of the time. He seemed to feel sockets on touch/full contact about 70% of the time. IF N/C (no contact) is used, NO ELECTRIC CURRENT WILL BE FELT. I don't need an unreliable device, so I'm giving 2 stars.
